SMIC 0.18um 1.8v Ring Oscillator Brief Specification
Overview
The present IP is a Ring Oscillator. Its output frequency is about 55 MHz. The frequency can be fairly accurate (?0%) by trimming the resistance. Its power supply is 1.8v ?0%. An external bandgap, which provides 0.308v reference voltage, is needed to make the Ring Oscillator function properly.
