Abstract
An RF power amplifier biasing circuit has a start ramp signal input, a main current source input, an auxiliary current source input, and a circuit output. A ramp-up capacitor is connected to the auxiliary current source input. A ramp-up switch transistor is connected to the start ramp signal input and is selectively thereby to connect the auxiliary current source input to the ramp-up capacitor. A buffer stage has an input connected to the ramp-up capacitor and an output connected to the main current source input at a sum node. A mirror transistor has a gate terminal corresponding to the circuit output and a source terminal connected to the sum node and to the gate terminal.
