Abstract

A time delay from a triggering event to switching of an output signal in a microelectronic device can be adjusted to compensate for various characteristics of the electronic device. The characteristics include temperature, voltage, and manufacturing process conditions. The time delay is adjusted using a variable delay circuit having multiple delay cells that are selectively coupled to control the time delay. The conditions of the electronic device are detected using a process sensor, which includes an oscillator having a frequency that is sensitive to variations in the conditions.
