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 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 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.

摘要： An input stage circuit and method provides voltage level conversion and overvoltage protection for an input stage circuit using a single gate oxide pass circuit and a single gate oxide voltage level shifting circuit. In one embodiment, the circuit and method includes receiving an input signal through the single gate oxide voltage pass circuit wherein the input signal can have a voltage level higher and lower than a first reference voltage for the voltage pass circuit. An output signal from the voltage pass circuit is provided to a single gate oxide voltage level shifting circuit that shifts a voltage level of the input signal from a first logic high level to a second lower logic high level when the input signal is above a reference voltage. The circuit and method provides a scaled output signal that has a maximum voltage level substantially equal to a reference voltage associated with the level shifting circuit when the input signal exceeds the reference voltage so that an output signal to a protected circuit, such as a core logic circuitry, is above an input signal less a threshold voltage drop that occurs through the voltage pass circuit. In another embodiment, hysteresis is added for an output signal from the voltage level shifting circuit to provide suitable noise reduction prior to the converted signal being passed to subsequent stages.
