Abstract

A wideband buffer is described which has improved slew rate over prior buffers. In one embodiment the buffer includes (a) complementary buffer subcircuit, (b) first and second current mirrors to bias the buffer subcircuit in a cross coupled manner, and (c) means of setting a stable quiescent operating point for the circuit.
