Abstract :
This paper presents a design of a transmitter pulse generator UWB-Ultra Wide Band in standard 180 nm MOSIS/CMOS technology. We proposed a pulse generator using Phase-Frequency Detector (PFD) that is designed using a modified architecture TSPC (True Single-phase Clock) positive edge triggered D Latch. The operation range and power consumption PFD is 45 ¿W to 2 mW, from 200 MHz to 5 GHz, respectively, and a minimum phase difference is 30 ps. Whole circuit has been simulated using LTSpice and the results had demonstrated the circuit capability to operate as an impulse generator. It generates pulses with 70 ps width. The Gaussian impulse achieves a very short pulse width of 133 ps, and amplitude of 48 mV. The generated pulse shape is similar to the 1st derivative. The complete design, occupies an area of 35400 ¿m2 including the inductor and without the PAD`s and a power consumption of 2 mW at 2.56 GHz@ 2 V supply voltage.
