A 90 nm CMOS V-Band Low-Noise Active Balun With Broadband Phase-Correction Techn

Abstract

This paper presents a V-band low-noise active balun with broadband phase-correction technique (PCT). The proposed technique effectively mitigates the phase deviation of active balun caused by parasitic imbalance and circuit mismatch. This tech- nique is insensitive to frequenc y, which makes the operation fre- quency of active balun with the PCT can be extended to millimeter- wave (MMW) band. Within the low noise current-reuse pre-ampli- fier, this active balun circuit can be employed as low-nois
