Abstract :
This paper proposes a new programmable delay cell (PDC) controlled by a 4-bit binary coding inverter array and a 4-bit binary coding capacitor array for the digital impulse radio (IR) ultra wide band (UWB) pulse generator. This proposed PDC can realize an extended tuning range of pulse width with an adjustable step and reduce the cost of chip area. Simulation results show that, when implemented in a TSMC 0.18μm technology, the minimum tuning range of pulse width is from 218ps to 398ps, while the maximum tuning range is from 327ps to 507ps, both have a linear step of 13ps.
