This paper proposes an embedded method of measuring process and temperature variations using the resulting change in transconductance of affected transistors. It also presents a compensation scheme for these variations using a generic and versatile method that can conveniently be used in system-on-chip applications. The measuring and compensating system has been applied on a 9-stage current-controlled oscillator. Differences in oscillating frequency between corner cases have been reduced from over 90 MHz to less than 10 MHz.
