Abstract
There is disclosed an amplifier circuit comprising: an amplifier having input and output terminals; a temperature dependent variable impedance unit comprising: a first terminal, a second terminal and a variable impedance unit control terminal; a transistor comprising a transistor control terminal coupled to the variable impedance unit control terminal; a first resistor coupled in parallel with the conduction channel; a capacitor coupled in series with the conduction channel between the conduction channel and one of: the first terminal; and the second terminal; and wherein: the first terminal is coupled to one of: the input terminal and the output terminal; the second terminal is for coupling to a reference node; and the variable impedance unit control terminal is configured to receive a control signal that is based on a measured temperature indicative of a temperature of the amplifier circuit and thereby provide a temperature dependent variable impedance for the amplifier circuit.
