摘要： An integrated circuit is capable of controlling a communication signal by using power ramp controlled communication buffer logic to generate an outgoing communication signal based on a detected voltage on a voltage source. The voltage source is necessary to supply power for power ramp controlled communication buffer logic. The voltage on the voltage source may be detected using power ramp sensor logic. The outgoing communication signal is based on a core logic output signal if the detected voltage is greater than or equal to a predetermined voltage level. If, the detected voltage is less than the predetermined voltage level, the outgoing communication signal is predetermined to be one of: a tristate outgoing communication signal, a logic one outgoing communication signal and a logic zero outgoing communication signal. Power ramp controlled communication buffer logic may also generate a core logic input signal based on an incoming communication signal in response to the detected voltage.

摘要： An input signal is routed to a first logic one reference signal generator or alternatively routed to a second logic one reference signal generator based at least one a voltage level of the input signal. When the voltage level of the input signal is less than a threshold value, the first logic one reference signal generator selectively generates a first logic one reference signal. When the voltage level of the input signal is greater than or equal to the threshold value, the second logic one reference signal generator alternatively generates a second logic one reference signal. The first and second logic one reference signals may be used to control a first voltage scaling circuit that drives a scaled output signal having a logic one value corresponding to the voltage level of the first logic one reference signal.

摘要： A buffer circuit utilizes a single gate oxide pre-buffer voltage level shifting circuit on, for example, an output buffer of an I/O pad, to accommodate different I/O pad supply voltages while maintaining normal operating voltages (degradation levels) across boundaries of single gate oxide devices that form the buffer. The single gate oxide output buffer can operate at several different supply voltages. A pre-buffer voltage level shifting circuit includes a multi-supply voltage level shifting circuit having signal gate oxide devices coupled to produce a pre-buffer output signal to an output buffer. A single gate oxide cross coupled active load is coupled to the multi-supply voltage level shifting circuit and provides suitable drive voltages to at least one of cascaded buffer transistors.

摘要： A powerup sequencing circuit and method generates an artificial supply voltage until the actual supply voltage is at a suitable level. An artificial supply source, such as a pull up circuit, is coupled to a node that receives a first supply voltage, such as an I/O buffer voltage. The pull up circuit is also coupled to an isolatable source voltage node. The isolatable source voltage node is the node that causes the actual second supply voltage. A temporary isolation circuit is operatively coupled to the pull up circuit and is operatively interposed between the node that receives the first supply voltage and the isolatable source voltage node. The pull up circuit provides a temporary or artificial second supply voltage level to an on chip circuit, such as an I/O buffer circuit or other suitable circuit that may, for example, be multi-voltage supply dependent. The temporary supply voltage is provided to the on chip circuit during powerup and the temporary isolation circuit operatively isolates the isolatable source voltage node until the second supply voltage reaches a suitable level and turns off the temporary isolation circuit.

摘要： A system and method for measuring integrated circuit (IC) temperature. An integrated circuit (IC) includes a thermal sensor and data processing circuitry. The thermal sensor utilizes switched currents provided to a reference diode and a thermal diode. The ratios of the currents provided to each of these diodes may be chosen to provide a given delta value between the resulting sampled diode voltages. At a later time, a different ratio of currents may be provided to each of these diodes to provide a second given delta value between the resulting sampled diode voltages. A differential amplifier within the data processing circuitry may receive the analog sampled voltages and determine the delta values. Other components within the data processing circuitry may at least digitize and store one or both of the delta values. A difference between the digitized delta values may calculated and used to determine an IC temperature digitized code.

摘要： An integrated differential receiver includes a single gate oxide differential receiver and an associated switchable voltage supply circuit. The integrated differential receiver determines the desired receiver supply voltage and selects a supply voltage for the single gate oxide differential receiver. When a lower supply voltage is determined as the desired supply voltage, the integrated differential receiver automatically provides a supply voltage to the single gate oxide differential receiver with a voltage higher than the I/O pad supply voltage and higher than the maximum input signal voltage to increase the speed of operation for the differential receiver. The switchable voltage supply circuit is operatively responsive to a control signal which indicates the desired supply voltage for the I/O pad. In one embodiment, both the single gate oxide differential receiver and the switchable voltage supply circuit are single gate oxide circuits.

摘要： A pre-buffer voltage level shifting circuit includes a multi-supply voltage level shifting circuit having single gate oxide devices coupled to produce a pre-buffer output signal to an output buffer. The pre-buffer output signal has a level within normal gate voltage operating levels of the single gate oxide devices for each of the least a plurality of supply voltages. In one embodiment, the multi-supply voltage level shifting circuit includes a current mirror coupled to at least one of the first or second power supply voltage and also uses a non-linear device, such as a transistor configured as a diode, which is coupled to the output of current mirror. The non-linear device is coupled to receive a digital input signal from a signal source, such as from a section of core logic. A switching circuit coupled to the non-linear device selectively activates the non-linear device based on a level of the digital input signal. The circuit, in effect, shifts the core logic supply voltage up to provide efficient and safe control of single oxide gate output buffer transistor devices, such as p-channel devices.
