Abstract :
A static CML frequency divider and a full differential low noise amplifier (LNA) with inductive peaking technique are designed for UWB system using SMIC 0.18-μm CMOS technology. Compact inductors are used for good performances and small chip area. Measurement results show that the operation range of divider is from 2 to 9GHz under 0dbm input power and power consumption is 3.6mW. The LNA achieves a peak power gain of 29.43dB with a -3dB bandwidth of 3-4.5GHz. The noise figure (NF) is 2.34-3.84dB while consuming 3.5mA of current from a 1.8-V supply. The core areas of proposed circuits are 0.13mm2 and 0.17mm2 respectively including buffers.
