摘要

A three-stage 60-GHz power amplifier (PA) has been implemented in a 65 nmrnComplementary Metal Oxide Semiconductor (CMOS) technology. High-quality-factor slowwaverncoplanar waveguides (S-CPW) were used for input, output and inter-stage matching networksrnto improve the performance. Being biased for Class-A operation, the PA exhibits a measuredrnpower gain G of 18.3 dB at the working frequency, with a 3-dB bandwidth of 8.5 GHz. Thernmeasured 1-dB output compression point (OCP_(1dB)) and the maximum saturated output powerrnP_(sat) are 12 dBm and 14.2 dBm, respectively, with a DC power consumption of 156 mW underrn1.2 V voltage supply. The measured peak power added efficiency PAE is 16%. The die area isrn0.52 mm~2 (875 × 600 μm~2) including all the pads, whereas the effective area is only 0.24 mm~2. Inrnaddition, the performance improvement of the PA in terms of G, OCP_(1dB), P_(sat), PAE and the figurernof merit using S-CPW instead of thin film microstrip have been demonstrated.
