Abstract
This article demonstrates a $W$ -band local-oscillator generation technique in 120-nm SiGe BiCMOS technology with high output power and high efficiency. The circuit employs a frequency quadrupler that is driven with differential quadrature inputs that are provided by either a quadrature voltage-controlled oscillator (QVCO) or a tunable active polyphase filter (PPF) circuit. The quadrupler employs a phase-controlled quadrature-push (PCQP) topology using stacked devices with a lower class-C common-emitter (CE) amplifier generating a current that is then modulated by an upper common-base (CB) amplifier driven out-of-phase with the lower devices. Such a structure generates a strong fourth-order harmonic. Four such stacks driven at their input using accurate differential quadrature signals increase the fourth-harmonic output power while suppressing other harmonics. The differential quadrature signals for the quadrupler are provided using either a PPF circuit or a capacitive injection-locking QVCO, which achieves wide tuning range and low phase noise. Both approaches are evaluated through the measurement of separate test circuits. The LO circuit using the QVCO provides 8–11.5-dBm output power over 75.2–83 GHz, power efficiency of 2.2–4.1%, including QVCO and buffer power, >20-dB harmonic rejection in the lower frequency range, and >14.4-dB harmonic rejection in the upper frequency range. The LO circuit using the active PPF provides 8.4–11.2-dBm output power over 75.6–82.8 GHz, power efficiency of 2.4–4.8%, including PPF and buffer power, and >23-dB harmonic rejection.Keywords
