摘要： A parameter monitor and method for monitoring a parameter of a passive component on an integrated circuit. The parameter monitor includes an oscillator circuit. The parameter monitor also includes circuitry configured to measure a first time period of an oscillation of the oscillator circuit with a passive component to produce a first digital count value, to measure second time period of an oscillation of the oscillator circuit without the passive component to produce a second digital count value, and generate a code indicative of a value of or a variation in the value of the passive component using the first and second digital count values.
