Abstract:
A biasing circuit with high current drive capability for fast settling of a biasing voltage to a stacked cascode amplifier is presented. According to a first aspect, the biasing circuit uses transistors matched with transistors of the cascode amplifier to generate a boost current during a transition phase that changes the biasing voltage by charging or discharging a capacitor. The boost current is activated during the transition phase and deactivated when a steady-state condition is reached. According to a second aspect, the biasing circuit uses an operational amplifier in a feedback loop that forces a source node of a cascode transistor of a reference circuit, that is a scaled down replica version of the cascode amplifier, to be at a reference voltage. The high gain and high current capability of the operational amplifier, provided by isolating a high frequency signal processed by the cascode amplifier from the reference circuit, allow for a quick settling of the biasing voltage.

Claim (Index 7):
The circuit arrangement according to  claim 1 , wherein coupling of the stacked cascode amplifier to the reference circuit is provided via respective series connected resistors that are configured to substantially isolate the reference circuit from the RF signal.
