Abstract
In this paper, a low flicker noise, 5 GHz Direct Conversion Receiver (DRC) has been designed utilizing Dynamic Current Injection (DCI) and tuning inductor in the mixing stage. This DRC has been designed in a TSMC 0.18 mu m 1P6M CMOS process for WLAN 802.11a applications. The proposed DRC achieves 7.4 dB SSB-NF, 28 dB Conversion Gain (CG), -10 dBm IIP3, and 1/f noise corner frequency of 100KHz with 80mW power consumption from 1.8V supply voltage. The active chip area was 1.9mm(2). All the simulations has been performed by Cadence Spectre simulator.
