Abstract
A 1-bit RF modulator using phase-modulated-carrier-clocking envelope ΔΣ modulation for a multi-mode/band transmitter is presented. The prototype IC designed in 90 nm CMOS process covers 2.4 GHz ISM and 3GPP frequency bands up to 3 GHz in conformity with IEEE 802.11g, W-CDMA and LTE in 5MHz-mode. The IC dissipates 8 mW for 1.95 GHz WCDMA and occupies 0.044 mm2.
