摘要： A high linear fast peak detector having a variable bias current and/or a variable bias voltage is described. In an exemplary design, the peak detector includes a transistor, a variable current source, a capacitor, and a feedback circuit. The transistor receives the input signal and provides a source current. The variable current source receives the input signal, provides high bias current when the input signal is low, and provides low bias current when the input signal is high. The capacitor is charged by the source current when the input signal is high and is discharged by the high bias current when the input signal is low. The feedback circuit receives a detected signal from the capacitor and provides higher bias voltage for the transistor when the input signal is high, which results in higher source current from the transistor.
