Abstract
A transmitter having a vertical BJT, capable of reducing power consumption, carrier leakage of a local oscillator and an error vector magnitude (EVM), is disclosed. In the transmitter, vertical BJTs implemented by a standard triplex well CMOS process are used in a frequency up-mixer and a baseband analog circuit including a DAC, an LPF, a VGA and a PGA, thereby improving the overall performance of the transmitter.
