Abstract
A circuit for multiplexing a selected one of a plurality of input signals to an output conductor includes a plurality of diamond follower input buffers each having an input terminal coupled to receive an input signal, respectively. A diamond follower output buffer has an output coupled to the output conductor. A feedback resistor is coupled between the output conductor and the outputs of the input buffers. A first current mirror has a control input coupled to a first current bias terminal of each input buffer, and a second current error has a control input coupled to a second current bias terminal of each input buffer. The first and second current mirrors have outputs connected to drive the input of the output buffer and bias current terminals of the output buffer to provide a high slew rate.
