Two types of power amplifiers are designed and implemented with TSMC CMOS 90 nm 1P9M process. An E-type power amplifier is designed for non-invasive glucose monitoring system. An AB-type power amplifier is designed for radio detection and ranging (RADAR) and the fifth generation mobile networks. A Power amplifier for microwave heating system is designed and implemented with TSMC CMOS 0.18 um 1P6M process.
A 28-30 GHz transmitter (Tx) is designed for non-invasive glucose sensing system. A two-stage Class-E power amplifier (PA) is composed with a drive stage and a cascode stage for better linearity. A buffer with transformer is designed for transforming the differential output of voltage-controlled oscillator (VCO) to single-end. The 1.05×1.34 mm2 transmitter is fabricated in TSMC CMOS 90 nm 1P9M process. The measurement result of the transmitter output power with 50 Ω probe is 10.3 dBm with PAE of 17.7% and power consumption of 84.5 mW from a 2-V supply.
A 2.4 GHz power amplifier is designed for microwave heating system with differential cascode topology. A voltage swing of 8 V on the load inductance is to drive electric field to heat the DUTs.
A 31 to 33 GHz two stage differential AB-type power amplifier for RADAR system is designed. Input transformer is designed for measurement. Output transformer is designed as single ended output for next stage. The output power of 8.5 dBm, gain of 17.41 dB and PAE of 23% are designed for the RADAR system.
