Abstract:
A circuit and a method for adjusting the performance of an integrated circuit, the method includes: comprising: (a) measuring the performance of a first monitor circuit having at least one field effect transistor (FET) of a first set of FETs, each FET of the first set of FETs having a designed first threshold voltage; (b) measuring the performance of a second monitor circuit having at least one field effect transistor (FET) of a second set of FETs, each FET of the second set of FETs having a designed second threshold voltage, the second threshold voltage different from the first threshold voltage; and (c) applying a bias voltage to wells of the FETs of the second set of FETs based on comparing a measured performance of the first and second monitor circuits to specified performances of the first and second monitor circuits.
