Abstract
A unified balun low noise amplifier (LNA) and I/Q mixer is provided as a single-chip design, and includes a passive/active gain-boosted balun-LNA-I/Q-mixer (blixer), a filter section and a buffer amplifier. The filter section includes an IF-noise-shaping transistorized current-mode lowpass filter sharing a common power supply with the blixer, which allows the blixer and lowpass filter to draw a single bias current. The filter section also includes a complex-pole load providing image rejection and channel selection.
