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...
This article combines theoretical calculation and ATP-EMTP simulation to design the 10/350μs Crowbar impulse current circuit. Parameters that affect peak value and tail time of the 10/350μs current are obtained. Methods to determine the best main circuit parameters are also concerned. with the increase of the main capacitance, the current peak value and the front time also increases; with the increase...
