AbstractWe present a fourth-order bandpass ΣΔ switched-current modulator IC in 0.8 μm CMOS single-poly technology. Its architecture is obtained by applying a lowpass to bandpass transformation (z-1 →-z-2) to a second-order lowpass modulator. It has been realized using fully-differential circuitry with common-mode feedback. Measurements show 8 bit dynamic range up to 5 MHz clock frequency and 10 KHz bandwidth.
