- Abstract
This Paper presented a novel differential CMOS cascaded power amplifier (PA) operated at 76.5 GHz frequency band for automotive Radar applications. PA consumes more DC power on the front side of the RF transmitter, so a highly efficient PA is required which have high output power for long range used in automotive Radar application. PA with high output power is the biggest challenges for designing. at mm-wave range. This paper described the three most important challenges of CMOS PA: low breakdown voltages, a low-quality factor of passive elements and low output swing in CMOS technology. It presents a new method to design Class E PA using three configurations: cascaded, differential, and parallel. Some basic parameters used for PA are also discussing in this paper. Post Layout Simulation results of the proposed PA is carried out over SpectreRF Cadence software. The circuit dissipates a total DC power of 64.8 mW from a 3.6 V power supply, 340 × 1130 µm2 layout area and the input/output return losses of the circuit at 76.5GHz frequency are −36 dB and −27 dB respectively. It provides 17 dBm output power, 20.4 dB power gain, 1.15 stability factor, and 3.1 dB noise factor
