Abstract: A low power frequency generating circuit including voltage control oscillator and frequency multiplier is provided to reduce a current consumption by simplifying a voltage source by a current reused mode. A low power frequency generating circuit includes a voltage control oscillator(21) and a frequency multiplier(22). The voltage control oscillator generates a frequency signal of a fixed range. The frequency multiplier receives the frequency signal generated in the voltage control oscillator, and outputs a frequency signal of an integral number multiple. The voltage control oscillator and the frequency multiplier are serially connected between a powered terminal and a ground terminal, and form a transmission path of a power current connected from the powered terminal to the ground terminal.

Abstract: A polar transmitter having a receiving function is provided to check a BER(Bit Error Rate) by using a receiver while a separate external BER measurer is unnecessary, and to calibrate amplitude and a phase for an optimal BER. A multimode baseband circuit unit(100) converts I(In-phase)/Q(Quadrature-phase) signals into amplitude and phase signals, and calibrates the amplitude and phase signals according to calibrated amplitude/phase and a BER of output signals in accordance with I/Q signals provided in calibration mode. A DA(Digital to Analog) converter(300) converts a digital amplitude signal into an analog amplitude voltage. A phase modulator(600) modulates a phase signal into an RF(Radio Frequency) signal for transmission. A power amplifier(700) amplifies the RF signal by determining a gain according to the amplitude voltage. A path selector(800) switches on a normal mode path as switching off a calibration mode path connected to the normal mode path in parallel in case of a communication mode, and switches off the normal mode path as switching on the calibration mode path in case of a calibration mode. A receiver(900) restores output signals incoming through the path selector into I/Q signals to provide the restored signals to the baseband circuit unit.
