Integrating audio and power management into a system-on-chip (SoC) is of interest due to reduced board area and cost. Integrated Class-D audio drivers need to drive high voltages to deliver high power across small loads; 525mW (5.8Vpp differential) across an 8Ω load working off the battery. Absence of highvoltage transistors along with high device noise(More)
A transformer-based receiver designed in 45nm CMOS that meets WCDMA, GSM, GPRS, and EDGE system requirements is presented. The receiver requires no interstage SAW filters and consumes 20mA from 1.4V. The use of a transformer at the LNA output helps achieve high linearity by lowering the voltage swing while simultaneously providing current gain. The analog(More)
