An UWB pulse generator using switching CMOS active inductor oscillator

A novel design of an Ultra Wide Band (UWB) pulse generator is presented. This topology is based on the switching of a CMOS active inductor oscillator. With the agreement of the desired specifications, the design technique of UWB pulse generator is described in this work. The achieved simulated results show the best performances of the proposed UWB pulse generator in terms of power consumption (22.6mW at 1.8V voltage supply), frequency bandwidth (530MHz), power spectral density (PSD) which is limited to -43.1dBm/MHz and the best agreement in Federal Communication Commission (FCC). This UWB pulse generator is implemented in a 0.18 μm CMOS process technology.
