The phase and gain imbalance of a balun output can be adjusted by a differential current balancer (DCB) circuit. The performance of DCB circuit, for correcting the phase (gain) imbalance, is analyzed for a wide range of input signal level, and the accuracy is verified with circuit simulation. To illustrate the phase-error/gain-error (PE/GE) correction, a 30–40 GHz DCB circuit is designed and simulated in a 180-nm CMOS process. The DCB is examined for input PE, Δ A , of − 2 0 ∘ ≤ Δ A ≤ + 2 0 ∘ and input GE, GA, of − 2 dB ≤ 2 0 ∗ log (1 + G A) ≤ + 2 dB. Analysis and simulation illustrate an output phase error (OPEDCB) of − 1 0 ∘ ≤ OPE DCB ≤ + 2 ∘ and output gain error (OGEDCB) of − 1 dB ≤ OGE DCB ≤ + 1. 5 dB, over frequency range of 20–50 GHz. The results of DCB circuit for PE (GE) compensation are compared to that of phase-correction technique (PCT) circuit, illustrating the superior phase (gain) imbalance correction of the DCB circuit with lower NF and DC power consumption.
