The design of an on-chip RC-based oscillator, implemented in a standard 0.35 mum CMOS process, without any external component, is presented. The proposed oscillator provides a clock signal at a frequency of about 80 KHz with a temperature coefficient smaller than 842 ppm/degC over a temperature range from 0 to 80 7degC and a standard deviation due to process variations smaller than 4%, without any external trimming. The proposed oscillator operates with a supply voltage of 1 V and has a power… CONTINUE READING
