Abstract
- A very simple, wide range and programmable pulse width controller or duty cycle corrector (DCC) is presented. Simulating the circuit in 0.35 μm Complementary MOSFET (CMOS) technology shows that the frequency range of the input signal can be within 250 MHz to 1.6 GHz, with a duty cycle of 30-70%. The proposed circuit generates an output signal with programmable duty cycle in the range of 30-70% with steps of 10% which could be extended to more steps by simple variations. The systematic peak-to-peak jitter at center frequency (1 GHz) is 1ps, while adding a random noise source of 5% of the power supply, increases it to 13 ps. the power consumption at maximum speed (1.6 GHz) is 4.9 mW. Monte Carlo simulations show maximum of 3.4% error at the 1.5 GHz input frequency and 70% output duty cycle. [ABSTRACT FROM AUTHOR]
