SYSTEMS AND METHODS MITIGATING TEMPERATURE DEPENDENCE OF CIRCUITRY IN ELECTRONIC DEVICES

摘要

Methods and systems for compensating for temperature variation in the performance of electronic circuits and systems are disclosed. In some embodiments, the systems are configured to store compensation parameters determined in calibration, where the compensation parameters are used by the systems to modify performance. In some embodiments, the systems are part of an automatic test equipment (ATE) system.

1. An electronic device, comprising:
an integrated circuit (IC) substrate; a plurality of circuits on the substrate, each comprising:
an input unit configured to receive one of a plurality of reference signals, andan output unit configured to generate an output signal, wherein at least one parameter of the output signal is dependent at least in part on the received one reference signal and on a circuit temperature, such that a change in the parameter in response to a change in the temperature is based partly on the reference signal; and a plurality of reference signal generators on the substrate, each reference signal generator configured to generate a reference signal for a corresponding one of the circuits, wherein each reference signal generator comprises:
an input unit configured to receive one of a plurality of control inputs, andan output unit configured to generate a reference signal for the corresponding one circuit, wherein the reference signal for the corresponding one circuit is dependent at least in part on the circuit temperature of the corresponding one circuit, and wherein the temperature dependence of the reference signal for the corresponding one circuit is based at least in part on the received one control input.
