Abstract:
1. A sampling differential amplifier for amplification of a signal having: (a) a signal input configured to receive an input signal to be amplified; (b) at least one signal amplification transistor having a control connection that is connected via a sampling capacitor to the signal input, each of the at least one signal amplification transistors being connected via series-connected load resistances to a positive supply voltage and via current source to a negative supply voltage; (c) a signal output configured to provide an amplified output signal, the signal output being tapped off the signal amplification transistors; and (d) at least one sampling switching transistor connected between a node between the series-connected load resistances and a control connection of the at least one signal amplification transistor, the at least one sampling switching transistor having a control connection connected to a control signal input for application of a sampling control signal.
