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 28):
The circuit arrangement according to  claim 27 , wherein substantial isolation of the reference circuit from the RF signal allows for a higher gain of the feedback loop.
