Abstract:
1. A wireless transmitter comprising: a transistor comprising a source, a gate, and a drain, wherein the gate is coupled to an input signal to be transmitted, and wherein the drain is coupled to a power supply voltage and to an antenna, wherein the transistor is configured to amplify the input signal and produce an output signal; a programmable feedback circuit having an input terminal coupled to the drain, an output terminal coupled to the gate, and a control input, wherein the programmable feedback circuit adjusts a series resistor and capacitor (RC) circuit between the gate and the drain of the transistor based on a control signal received on the control input, wherein the programmable feedback circuit is configured to produce a first RC circuit value when the wireless transmitter is configured to produce a first power supply voltage to the drain of the transistor, and wherein the programmable feedback circuit is configured to produce a second RC circuit value to change a negative feedback from the drain to the gate when the wireless transmitter is configured to produce a second power supply voltage to the drain of the transistor.
