Abstract

The present invention comprises a method and apparatus for boosting an input signal to an output signal with a variable gain according to a supply voltage. The circuit comprises a detector and a voltage booster. The detector detects the supply voltage and generates a control signal having a value dependent on a difference between the detected supply voltage and a critical supply voltage. The critical supply voltage is temperature insensitive. The voltage booster is coupled to the detector for generating an output signal having a gain relative to the input signal. The gain is dependent on the value of the control signal.
