Abstract:
An input current is applied to a ladder network comprising diode-connected-transistor shunt legs and resistive series arms. The network derives from the input current a bias current having an amplitude which is a fraction of the input current and supplies that bias current to the base-emitter junction of an amplifier transistor.
