Abstract(in English) | This paper describes a second-order continuous-time ΔΣ modulator for a W-CDMA receiver, which operates at a supply voltage of 0.9 V, the lowest so far reported for W-CDMA. Inverter-based balanced OTAs without using differential pair are proposed for a low-voltage operation. Circuit parameters are optimized by system simulations. The modulator was implemented in a 0.13-μm CMOS technology. It consumes only 1.5 mW. The measured SNDR is 50.9 dB over a bandwidth of 1.92MHz. |
