A quad-band GSM/GPRS/EDGE receiver, implemented in 65 nm CMOS, complies with the ETSI standard without the need of external SAW filters. By exploring the properties of passive mixers and current-mode operation from RF to baseband, the receiver can achieve a SAW-filter-like selectivity with inexpensive on-chip components such as resistors and capacitors.

Due to their inherent anti-aliasing properties and potential for low-power design, continuous-time (CT) ΔΣ ADCs are an indispensable component in wireless communication systems such as GSM/WCDMA, since a precise sampling network is not required. However, conventional CT ΔΣ ADCs suffer from 2 main problems: 1) high sensitivity to clock jitter, and 2) excess(More)
A 40 nm CMOS transceiver supports 10 bands of HSPA+ and quad-band GSM/EDGE occupying 6.2 mm<sup>2</sup> of a Modem SoC. The TX supports up to 11 Mb/s HSUPA with minimal analog filtering and &lt;;35 mA battery current DG-09 weighted. Receive diversity with dual cell HSDPA supports up to 42 Mb/s downlink. The RX path is inductorless and achieves -111 dBm(More)
