Abstract
The present disclosure describes a system, a circuit, and method for process and temperature compensation in an integrated circuit. For example, the system includes a bus, a data latch, and a voltage generator. The data latch includes a plurality of transistors coupled to the bus. The voltage generator includes a tracking transistor with one or more physical characteristics that substantially match one or more respective physical characteristics—e.g., gate width and gate length dimensions—of at least one of the plurality of transistors in the data latch. The voltage generator is configured to adjust a pre-charged voltage on the bus based on an electrical characteristic of the tracking transistor.
