摘要 |
A power control module receives a dynamic power control signal and generates a differential bias signal proportional to the dynamic power control signal. An analog multiplexer receives a digital amplitude signal including n bits and receives the differential bias signal. The analog multiplexer multiplexes the digital amplitude signal with the differential bias signal in parallel and generates a first differential signal. A driver module receives the first differential signal and a second differential signal. The driver module generates a first drive signal proportional to the dynamic power control signal when a bit in said digital amplitude signal is a logic one and the driver module generates a second drive signal proportional to the second differential signal when a bit in said digital amplitude signal is a logic zero.
