摘要： A sensor power management arrangement includes a signal processing circuit configured to receive signal from a sensor, to test the signal against at least one criterion, and to pass the signal for further processing in response to the signal passing the at least one criterion. In this way, only signals that are of a sufficient importance or significance will consume the maximum amount of processing energy and through processing by later processes or circuitry. Should a signal from a sensor not be strong enough or meet other criteria, power will not be wasted in preparing that signal for provision to the microcontroller or microprocessor. Additional flexibility in the sensor power management can be realized by adjusting the criteria against which the sensor signal is compared based on a status of the sensor apparatus.

摘要： A battery detect circuit (32) is provided that is operable to dispose a sense resistor (50) in series with the battery to determine whether the charge is being provided to the battery or being extracted from the battery. The voltage across the sensor resistor (50) is sensed by a voltage/frequency converter (52). The voltage/frequency converter (52) is a differential structure comprised of two integrator structures (102) and (104) that are operable to utilize a switched capacitor configuration to drive comparators on the output thereof. Each of the integrator structures (102) and (104) has associated therewith passive elements and active elements. The integrators (102) and (104) have associated therewith integration capacitors (147) and (149). Additionally, there are two operational amplifiers (143) and (145) that provide the active components of each of the integrators (102) and (104). The various switched capacitor circuits (161) and (163) associated with the amplifiers (143) and (145) are provided to provide the integration operation. Both the amplifiers (143) and (145) and their associated switched capacitor circuits (161) and (163) are dynamically balanced such that they are switched between integrator (102) and integrator (104) on a periodic basis. This therefore allows the errors between the active and passive elements to be switched between the two integrators (102) and (104) such that no accumulative error occurs.
