摘要： A method for converting a multi-bit digital value to an analog value. The method includes, in a first conversion cycle, converting a first set of digital bits to a first analog voltage using passive charge-sharing. The method also includes, in a second conversion cycle, converting a second set of digital bits to a second analog voltage added to the first analog voltage using active charge-sharing. The first set of digital bits and the second set of digital bits are different bits of the multi-bit digital value.

The main integrated chip has a reference voltage source that generates a bias current. The secondary integrated chip has a second thermal diode that receives the bias current and based thereupon generates a second thermal sensed voltage and a second reference voltage that is proportional to a temperature of the secondary integrated chip. A digital thermal sensor within the main integrated chip determines a temperature of the secondary integrated chip based upon as comparison of the second thermal sensed voltage and the reference voltage.

摘要： A thermal sensing system includes a circuit having a layout including standard cells arranged in rows and columns. First and second current sources provide first and second currents, respectively. The thermal sensing system includes thermal sensing units, first and second switching modules, and an analog to digital converter (ADC). Each thermal sensing unit is configured to provide a voltage drop dependent on a temperature at that thermal sensing unit. The first switching module is configured to select one of the thermal sensing units. The second switching module includes at least one switch controllable by a control signal. The at least one switch is configured to selectively couple the thermal sensing units, based on the control signal, to one of the first and second current sources, via the first switching module. The ADC is configured to convert an analog voltage, provided by the selected thermal sensing unit, to a digital value.

摘要： A driver utilizes selective biasing of the terminal of an operational amplifier to reduce offset in the operational amplifier output. Each operational amplifier input includes a differential input pair of transistors including a NMOS transistor and PMOS transistor. At low and high ends of the input voltage range these transistors are selectively and individually coupled to either a standard input or biased to be on so as to contribute offset for offset compensation. The transistors are biased in a conventional manner for input voltages between the low and high ends of the voltage range.
