Abstract :
This paper presents a fully-integrated spread-spectrum clock generator (SSCG) with triangular modulation. This SSCG with spread ratios of 0.5% and 1% has been fabricated in 0.35mum double-poly quadruple-metal CMOS process. It consumes 140mW at 400MHz output from the supply of 3.3V. The required capacitance is equivalently reduced by a factor of 10 compared with the conventional one
