Abstract

Dual-band and wide-band receiver-front-ends (RFEs) using transformer-based current-gain-boost techniques are designed in 0.13μm CMOS. With a single switchable 3-coil transformer, the first dual-band RFE prototype measures NF of 2.5dB and 3.5dB and voltage gain of 20.7dB and 17dB at 1.7GHz and 3.8GHz, respectively. The second wide-band RFE achieves 0dBm IIP3 with 4dB NF and 13dB voltage gain over a frequency range from 2GHz to 5GHz.
