Abstract:
A current mirror circuit for biasing a power amplifier includes a modified Wilson current mirror with a pair of first and second mirror transistors connected to a third transistor. The first mirror transistor is configured for operating in a saturation mode, with a gate voltage of the first mirror transistor being lower than a gate voltage of the power amplifier. The third transistor charges the power amplifier circuit during a positive half cycle of an input signal and the first mirror transistor discharges the power amplifier circuit during a negative half cycle of the input signal at different rates.
