Title:

SINE WAVE MULTIPLICATION DEVICE AND INPUT DEVICE HAVING SAME

Document Type and Number:

WIPO Patent Application WO/2016/167146

Kind Code:

A1

Abstract:

Provided is a sine wave multiplication device of simple configuration, broad input signal level range, and minimal fluctuation in characteristics due to temperature. A signal component that corresponds to the product of an input signal Si and the third harmonic of a first square wave W1 included in an output signal Su1; and a signal component that corresponds to the product of the input signal Si and the fifth harmonic of the first square wave W1 is canceled by: a signal component that corresponds to the product of the input signal Su1 and the fundamental wave of a second square wave W2 included in an output signal Su2; and a signal component that corresponds to the product of the input signal Si and the fundamental wave of a second square wave W3 included in an output signal Su3.
