Abstract

CMOS-based near zero-offset multiple inputs maximum circuit and minimum circuits are proposed. The analog signal building blocks including shunt-feedback buffer, voltage-subtraction circuits and current mirrors are deployed for obtained the good performances. This achieved circuit is a simply scheme and able to work with low-power supplies. The input range is obtained around ±600 mV within ±1.5 V power supplies. Near zero-offset and low-output impedance are provided by proposed circuit. The delay of output is less than 5 ns for THD less than 1% and frequency response up to 500 MHz. Half-wave, full-wave rectifiers and 4 bits linear combination Digital-to-Analog Converter (DAC) are raised up to confirm the realistic applications. All performances including the DC-characteristic, frequency response, high-frequency wave output are simulated by PSpice.
