ABSTRACT:
A method and apparatus for providing a high speed buffer with high gain bandwidth and rail-to-rail operation is disclosed. Resistor-capacitor (RC) filters are added in current mirrors that are in the signal path. The effect of these filters is to create a frequency-dependent impedance that extends the gain bandwidth of the circuit.
