Analog Integrated Audio Frequency Synthesizer
(2016) p.83-86- Abstract
In this paper we present an audio synthesizer that creates audio signals, intended to be reproduced as sound by a loudspeaker. This paper details the design, implementation and verification of an analog, subtractive audio synthesizer. The synthesizer produces a variety of waveforms spanning approximately 3 octaves. The frequency is controlled by an external voltage and the harmonic content is regulated by a tunable filter. The system is fabricated in 130 nm CMOS. Current consumption measures between 1.8 and 2.1 mA from a supply of 1.2 V.
