Abstract :
In this paper the design of a voltage-mode switching mode amplifier in a 65-nm CMOS process in the GHz range is described. The amplifier can be operated with a rectangular drive signal with 50 % duty cycle up to 4 GHz and pseudo random bit sequences up to 4 GBit/s. The calibrated broadband PAE of the amplifier chip is 22 % at 2 GHz, 13 % at 3 GHz and 7 % at 4 GHz for a rectangular drive signal with 50 % duty cycle. The broadband output power into 50 Ω is 15.3 dBm for 2 GHz, 14 dBm for 3 GHz and 12 dBm for 4 GHz for a single ended measurement.
