Abstract
In a current-controlled type division circuit, an auxiliary transistor is employed in conjunction with a division control transistor to allow a divisor signal, which normally flows through the division control circuit, to flow through the auxiliary transistor in the case when a division controlling signal applied to the base of the division control transistor falls below a predetermined level. By the provision of the auxiliary transistor, the divisor signal of a predetermined minimum is adapted to be flown therethrough to prevent the gain of the division circuit from exceeding a predetermined maximum.
