Abstract
An integrated circuit includes a power amplification circuit and a switch circuit wherein the switch circuit is coupled to an output of the power amplification circuit, a bypass input, and a control input, such that the switch selectively couples the power amplification circuit output or the bypass input to an output of the integrated circuit.
Claims1
An integrated circuit comprising
- a power amplification circuit;
- a first switch circuit coupled to an output of the power amplification circuit, a bypass input, and a control input, such that the switch selectively couples the power amplification circuit output or the bypass input to an output of the integrated circuit;
- a current source coupled to the bypass input;
- a calibration resistor;
- and
- a second switch coupled to the current source, the calibration resistor, and a second control input such that the second switch selectively couples the current source to the calibration resistor.
