    摘要: Various systems and methods for temperature measurement are disclosed. For example, some embodiments of the present invention provide temperature measurement systems. Such temperature measurement systems include a variable current source and a diode connected transistor. The variable current source is capable of applying two or more distinct currents to the diode connected transistor. The currents result in a different base-emitter voltage on the diode connected transistor. The systems further include an n-factor coefficient register and an analog to digital converter.

    摘要: A differential amplifier includes a differential input pair (2A) coupled to a folded cascode stage (2B) and a common mode feedback circuit (34) including a tracking circuit (30A) coupled to first (Vout−) and second (Vout+) outputs of the folded cascode stage (2B). The first and second outputs are coupled to first terminals of first (31A) and second (31B) tracking capacitors which have second terminals on which a first common mode output signal (VCM1) is produced and also are coupled to first terminals of third (32A) and fourth (32B) tracking capacitors, respectively, which have second terminals on which a second common mode output signal (VCM2) is produced. The first and third tracking capacitors are discharged by first (27A) and second (27B) switches that directly couple the first and second outputs to first and second inputs of a common mode feedback amplifier (4). A desired common mode output voltage (VCM-IN) is applied to a third input of the common mode feedback amplifier. The switches are opened to cause the first and second common mode output voltages to be generated, causing a common mode feedback control signal (VCMFB) to be generated for biasing the folded cascode stage.
