Abstract
The present disclosure includes programmable stabilization circuits and methods. In one embodiment, a power amplifier in a wireless transmitter includes a transistor comprising a gate, a source, and a drain. Feedback from the drain to the gate is modified dynamically to stabilize the amplifier under changing operating conditions. In one embodiment, a series RC circuit is configured between the drain the gate and the RC circuit value is adjusted based on different power supply voltage modes.
