Abstract

An analog sine wave generator based on a digital resonator and a bandpass delta-sigma (ΔΣ) modulator is presented. Except for a 1-bit D/A, this design is entirely digital allowing precise control over the amplitude and frequency of oscillation. Furthermore, it is area efficient as it does not require a ROM or a multiplier. Unlike previous designs, this circuit is capable of operating at any ratio of the clock frequency. We envision that this device will be used in communications circuits or as a test stimulus for mixed-signal ICs
