Abstract

Low distortion filters and oscillators that are useful for testing high-resolution ADCs are demonstrated in a 0.6 $\mu \text{m}$ CMOS process. Band-pass filter prototypes with center frequencies of 1 and 10 kHz have 60 dB attenuation at the second harmonic, THD $\mu \text{V}$ rms output noise. The oscillator prototype can generate 1 or 10 kHz and has THD $\mu \text{V}$ (45 $\mu \text{V}$ ) at 1 kHz (10 kHz).
