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.

In a braking force control system for a vehicle having a braking system capable of controlling braking force of each of right and left front wheels and right and left rear wheels independently of one another, when anti-skid control starts being performed on one of the front wheels while the vehicle is running on a road having different coefficients of friction on the left side and right side thereof, increase of the braking force of the other front wheel laterally opposite to the above-indicated one front wheel is suppressed, and increase of the braking force of at least one of the right and left rear wheels is suppressed.
