A transistor amplifier circuit, which includes means for adjusting the emitter current and therefore for varying the gain of an amplifying transistor in the circuit, comprising a semiconductor junction connected in parallel with the input of the transistor so that the variable mismatch that it is essential for the gain variation to occur substantially between the impedance of the semiconductor junction and the impedance of the transistor, whereby the input impedance to the amplifier can be kept substantially constant.
