Two different frequency doubling power amplifier topologies have been compared, one with differential input and one with single-ended, both with single-ended output at 60 GHz. The frequency doubling capability is valuable from at least two perspectives, 1) the high frequency signal is on the chip as little as possible 2) the voltage controlled oscillator and power amplifier are at different frequencies easing the isolation of the two in a transceiver. The topologies have been simulated in a 1p8M 130-nm CMOS process. The resonant nodes are tuned with on-chip transmission lines. These have been simulated in ADS and compared to a standard Cadence component, tline3. The Cadence component gives a somewhat pessimistic estimation of the losses in the transmission line. The single ended input amplifier outputs a maximum of 3.7 dBm and draws 27 mA from a 1.2 V supply, while the one with differential input outputs 5.0 dBm and draws 28 mA. The 3-dB bandwidth of the amplifiers are 5.9 GHz and 6.8 GHz, respectively.
