A combinational biasing technique is presented for a 400–450 MHz power amplifier (PA). By combining two class AB amplifiers with different conduction angles and optimising the design parameters as well, the 5th and 6th harmonics are greatly suppressed in the PA's output. The designed PA is fabricated in 65 nm CMOS technology. Measurement results show that with the presented technique the 5th and 6th...
A 10 Mbps OQPSK transceiver working in the 400–450 MHz frequency range is designed for medical telemetry applications requiring wireless communication with both high data rate and low power consumption. An inverter based phase-switching transmitter has been proposed to lower the transmitter power consumption. Moreover, a digital-assisted DC offset calibration (DCOC) technique that combines the PGA-gain-uncorrelated...
