A feedback control-loop system that employs an active DC output control circuit is disclosed which compares an input parameter measurement against a target specification associated with the input parameter measurement. In one embodiment, the active DC output control circuit receives an input signal for laser bias adjustment. In another embodiment, the active DC output control circuit receives a motor speed input from a source, such as a tachometer, for motor speed adjustment. In another embodiment, the active DC output control circuit receives an input power amplifier measurement for wireless applications.

Active DC output control and method for controlling targeted applications

A control loop system is provided that employs an active DC output control circuit that more accurately calibrates the desire voltage at a load, e.g. 3.3 volts, by adjusting a trim pin on a DC/DC converter. In a first embodiment, an active DC output control circuit calibrates a DC/DC converter that is connected to a single load. In a second embodiment, an active DC output control circuit calibrates multiple DC/DC converters that are connected to multiple loads.

Active DC output control and method for DC/DC converter

Analog integrated circuits have their individual characteristics compensated by the settings of self-contained non-volatile memory elements. The settings of the memory elements are determined by repeatedly testing the possible values until an optimal one is chosen. The testing process is accelerated by eliminating the need to re-write the non-volatile memory for each value that is tested.

Method and system for reduction of test time for analog chip manufacturing

A method and apparatus for tracking and controlling one or more voltage and current supplies during a transition between and off-state to an on-state, or from an on state to an off-state, is enabled by detecting a voltage or current transition and controlling the voltage or current supply transition within a specified upper and lower limit about a reference transition.

Method and apparatus for tracking and controlling voltage and current transitions

A configurable integrated circuit and method for trimming a desirable combination of analog and digital functions and customizing pin assignments by programming nonvolatile memory. Functional enhancement and chip compatibility are achieved by configuring an integrated circuit with specified analog and digital settings for operation with an external chip. Multiple NV registers with designated bits that correspond to activating, deactivating, trimming, or changing analog functions including internal voltages, bandgap, and oscillating frequencies.
