Abstract
The invention relates to an amplification circuit, comprising: a differential amplifier (241) having a first input node (236) and a second input node (240) for receiving respectively first and second input signals and an output node for producing an output signal; and active bias circuitry (250) connected to said differential amplifier (241) for drawing a bias current therefrom, wherein said active bias circuitry (250) is configured to draw an increased current when said first and second input signals are substantially equal. An oscillator comprising said amplification circuit and a circuit comprising an oscillator of said type is also part of the invention.
