| Keywords: | Switched-Current Circuits BandPass Sigma-Delta Modulation |
| Publisher: | Institute of Electrical and Electronics Engineers |
| Description: | We present a Switched-Current (SI) fourth-order bandpass ΣΔ modulator IC prototype. It uses fully-differential circuits in 0.8μm CMOS technology to obtain a Dynamic Range (DR) larger than 55dB at 2.5MHz center frequency with 30kHz bandwidth - in accordance to the requirements of AM digital receivers. The prototype incorporates a single-ended to fully-differential current-mode buffer for testing purposes. The power consumption of the whole prototype (modulator plus buffer) is 60mW from a 5V supply voltage. This work has been supported by the European Union, under ESPRIT Project 8795-AMFIS.
