Abstract

PURPOSE:To achieve a frequency doubler with a simple circuit constitution suitable for circuit integration, by applying a complementary signal to input terminals of a differential amplifier and wave-shaping double frequency signal obtained at a common connecting point. CONSTITUTION:Complementary input signals (a),(b), are inputted to the base of transistors (TR)1,2 constituting a differential amplifier, and a common connecting point (c) of the emitter is grounded via a constant current source 3. At the connecting point (c) with this constitution, a signal having potential lower than the base to emitter forward voltage drop of the TRs1,2 from the input signal in higher potential among the complementary input signals (a),(b), is obtained. Thus, the signal at the connecting point (c) has twice frequency as the input signal, and a double multiplied signal of the input signal can be obtained a terminal (d) by giving the double frequency signal to an amplifier or a logical gate circuit 4. The arrangement of the TRs1,2 with this constitution can be obtained easily through circuit integration.
