Abstract: The invention provides a control method for generating variable operating currents in relation to input signal power and output signal power and achieving both low noise and low power consumption. Emitter follower circuits are attached to output terminals of a frequency divider for generating a local signal. By adjusting the currents flowing through the emitter follower circuits, the amount of currents flowing into mixers is adjusted. When the amount of currents of local signals flowing into the mixers increases, the effect of noise suppression is expected. The amount of the currents flowing through the emitter follower circuits is changed depending on the amplification factor of variable amplifiers.

Abstract: A high-frequency power amplifier which can reduce a variation of power gain due to the dependence on gate length of a power amplification field effect transistor is provided. The high-frequency power amplifier comprises, over a semiconductor chip, a bias control circuit, a bias transistor and an amplification transistor which are coupled so as to configure a current mirror circuit, and a gate length monitor circuit comprising a replicating transistor. The amplification transistor amplifies an RF signal and a bias current of the bias control circuit is supplied to the bias transistor. The transistors are fabricated by the same semiconductor manufacturing process, and have the same variation of gate length. The gate length monitor circuit generates a detection voltage depending on the gate length. According to the detection voltage, the bias control circuit controls the bias current, thereby compensating the gate length dependence of transconductance of the amplification transistor.

Abstract: A high frequency circuit and a high frequency module are provided, in which the accuracy of compensation operation is improved in compensating by digital control. The amplification gain of an amplification element of an amplifier unit is controlled by a bias current of a bias control unit. A process monitoring circuit of a calibration circuit includes a first and a second element characteristic detector and a voltage comparator. The detectors convert the current of replica elements into a first and a second detection voltage. The voltage comparator compares a first and a second detection voltage and supplies a comparison output signal to a search control unit. Responding to the comparison output signal of the comparator and a clock signal of a clock generating unit, the controller generates a multi-bit digital compensation value according to a predetermined search algorithm, and the bias control unit of the second detector is feedback-controlled.
