Abstract:
1. A current-controlled CMOS (C3MOS) wideband data amplifier circuit, the circuit comprising: a first differential transistor comprising a source, gate, and drain; a second differential transistor comprising a source, gate, and drain; a current source that is coupled to both the source of the first differential transistor and the source of the second differential transistor; a first output impedance, comprising a first output resistor and a first shunt peaking inductor connected in series, that is coupled between the drain of the first differential transistor and a supply voltage; a second output impedance, comprising a second output resistor and a second shunt peaking inductor connected in series, that is coupled between the drain of the second differential transistor and the supply voltage; a differential termination impedance that is coupled between the gate of the first differential transistor and the gate of the second differential transistor; a first input impedance that is coupled between a first differential input of the C3MOS wideband data amplifier circuit and the gate of the first differential transistor; and a second input impedance that is coupled between a second differential input of the C3MOS wideband data amplifier circuit and the gate of the second differential transistor.
