摘要: A 2.4 to 10.7 GHz wideband mixer for multi-band orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) applications is designed using a TSMC 0.18 mu m CMOS technology. The designed mixer uses a LC folded cascode structure and a feedforward compensated high-linearity differential transconductor to improve the linearity. The measured results reveal that the proposed mixer achieves power conversion gain of 3.3 +/- 1.5 dB, third-order input intercept point (IIP3) of 6.9 dBm, and input l-dB compression point (P-1dB) of -2.8 dBm in the power consumption of 14.4mW from a 1.8V power supply. The chip area is 0.70 x 0.58 mm(2).
