ABSTRACT:
A transconductance input apparatus energized by supply voltage has an input for receiving an input signal, and an output for delivering an output signal. The apparatus also has a plurality of transconductance stages for converting the input signal into the output signal, which is substantially free of dead zones when the total supply voltage is 2.7 volts or less.
