A circuit is provided for multiplying a frequency by a cascade formed of a transadmittance having a transfer characteristic and a transimpedance having a transfer characteristic. The transadmittance includes two terminals for a signal of a first frequency and the transimpedance includes two terminals for a signal of a second frequency. A transfer characteristic of the transimpedance is steeper than a transfer characteristic of the transadmittance, and a modulation region of the transadmittance is larger than a modulation region of the transimpedance.
