    摘要： A circuit and a method for adjusting the performance of an integrated circuit, the circuit includes: first and second sets of FETs having respective first and second threshold voltages, the first threshold voltage different from the second threshold voltage; a first monitor circuit containing at least one FET of the first set of FETs and a second monitor circuit containing at least one FET of the second set of FETs; a compare circuit adapted to generate a compare signal based on a performance measurement of the first monitor circuit and a performance measurement of the second monitor circuit; and a control unit adapted to generate a control signal to a voltage regulator based on the compare signal, the voltage regulator adapted to supply a bias voltage to wells of FETs of the second set of FETs, the value of the bias voltage based on the control signal.
