Title:
METHOD AND APPARATUS FOR PRODUCING TRIANGULAR WAVE WITH LOW AUDIO BAND NOISE CONTENT
Document Type and Number:
Japanese Patent JP2013211891
Kind Code:
A
Abstract:

To provide an apparatus and method for generating a triangular wave with low audio band noise content for class D amplifier circuits.

A triangular wave generator 24 comprises an active integrator 27 and a feedback circuit network 26. The active integrator 27 receives a square wave clock input and generates a triangular wave output. The active integrator 27 is connected with the feedback circuit network 26. Audio band noise content is reduced without significantly sacrificing linearity of the triangular wave output.
