Abstract

A system for acquiring environmental information measurements. The 5 system (100) utilize a sensor, (205) a front-end circuit, (310) a loop filter (315), a switch controller (206), and a reduced-order loop control circuit to provide reliable data measurements while providing robust system behavior. The system further includes a sensor simulator (330) for simulating the operation of the sensor (205) and testing the operation of the front-end circuit (310) and the loop filter (315).

Claims8

Dependent claims

An apparatus for recording environmental data measurements, comprising:

a sensor for detecting environmental data;
a controller for controlling the operation of the sensor, the operation of the sensor including a plurality of operation modes automatically selected by the controller, wherein the controller further comprises:
a front-end circuit coupled to the sensor;
a loop filter coupled to the front-end circuit;
a multiphase clock generator coupled to the front end circuit and the loop filter;
a startup sequencer coupled to the loop filter and the multiphase clock generator;
a sensor simulator for simulating the performance of the sensor coupled to the startup sequencer, the multiphase clock generator, and the front-end circuit;
and
an overload detection device coupled to the loop filter and the startup sequencer.
