In this paper, 45 GHz and 60 GHz power amplifiers (PAs) with high output power have been successfully designed by using 90 nm CMOS process. The 45 GHz (60 GHz) PA consists of two (four) differential stages. The sizes of transistors have been designed in an appropriate way so as to trade-off gain, efficiency and stability. Due to limited supply voltage and(More)
A 60-GHz 4-bit vector-summing phase shifter has been implemented in a 90-nm CMOS process. Based on a tunable current-splitting technique with π-type low-pass filter (LPF) and T-type high-pass filter (HPF), a quadrature adjustable amplitude generator is developed to improve the insertion loss and adjust quadrature signals' amplitudes. Variable gain(More)
