Abstract: An apparatus and method for regulating a voltage to a load to compensate for one or more parasitic impedances. A first amplifier measures the voltage drop due to a first parasitic impedance, and a second amplifier measures the voltage drop due to a second parasitic impedance. An offset generator sums the first and second voltage drops with a reference voltage, and drives a DC-to-DC converter to produce an input voltage matching the summed voltages. Accordingly, the voltage at a load between the parasitic impedances matches the reference voltage. The load may be, for example, a computer microprocessor or central processing unit.

Abstract: A novel battery monitoring device is described. The monitoring device determines amount of battery self-discharge, determines amount of battery discharge from a monitoring circuit, determines amount of battery discharge from a host device when the host device is in a first power consumption mode, and determines amount of battery discharge from the host device when the host device is in a second power consumption mode. The first mode causes greater discharge of the battery during a given period of time than the second mode.

Abstract: A low power consumption oscillator circuit. The oscillator circuit comprises a capacitor coupled to a first resistor that is capable of delaying discharge of the capacitor. The oscillator circuit further comprises a first inverter coupled to the capacitor and having a first input. The first inverter is capable of applying charge to the capacitor when a first voltage potential on the first input is above a first threshold voltage of the first inverter. The first inverter is capable of removing charge from the capacitor when a second voltage potential on the first input is below a second threshold voltage of the first inverter. The oscillator circuit further comprises threshold detection circuitry having a second circuitry is coupled to the first input of the first inverter, and the second input is coupled to the capacitor.
