Abstract
A low-noise amplifier is disclosed. The amplifier includes a signal amplifier having an amplifier signal output, a first filter capacitor, a buffer amplifier having a buffer amplifier input and a buffer amplifier output; and a switching network. The first filter capacitor has first and second terminals. The second terminal is connected to a power rail. The amplifier signal output is connected to the buffer amplifier input by a first direct current path and the buffer amplifier output to the first terminal of the first filter capacitor by a second direct current path during a first time period. The amplifier signal output is connected directly to the first terminal of the first filter capacitor by a third direct current path during a second time period, and the amplifier signal output to the first terminal of the first filter capacitor through a resistor during a third time period.
