This paper presents a widely tunable balanced-to-unbalanced (balun) bandpass filter (BPF). The proposed balun uses two 2-port N-path BPFs with embedded quadrature phase shifting to achieve the single-ended to differential conversion. Analytical expressions for the in-band (IB) differential to single-ended (DS) and single-ended to differential (SD) voltage gains are derived and validated. A prototype balun is implemented in a CMOS 65 nm technology and it occupies an active area of approximate to 0.7 mm(2). Post-layout simulations show a common mode rejection of approximate to 50 dB during the DS mode of operation. During the SD mode of operation, the balun has a phase imbalance of < 2.5 degrees and an amplitude imbalance of < 0.2 dB over the tuning range of 0.1-1 GHz. |
