摘要： A method for monitoring various parameters and conditions of a rechargeable battery to accurately determine the remaining charge level of the rechargeable battery, and includes using a temperature sensor to monitor the temperature of the rechargeable battery. The potential level of the rechargeable battery is monitored with a voltage meter coupled to the rechargeable battery. The current flow into and out of the rechargeable battery is monitored with current meter coupled to the rechargeable battery. A current accumulator coupled to the current meter is used to accumulate the net total of current flow, an oscillatory circuit is used to generate a timing signal to time selected functions, and a timestamp will be generated indicative of a time when the battery ceases to be charged such that a self discharge correction is capable of being calculated.

摘要： A rechargeable battery pack with low powered, gas gauge circuitry for monitoring and accumulating various operating parameters of the rechargeable battery pack, includes a current monitor for measuring the current flow into and out of a battery cell in the rechargeable battery pack. An integrated current accumulator connected to the current monitor is used to maintain a measure of the net charge having flowed into and out of the battery cell. A charging current accumulator, which is also coupled to the current monitor, is used to maintain a measure of the total charge having flowed into the battery cell, while a discharging current accumulator is used to maintain a measure of the total charge having flowed out of the battery cell. A highly accurate oscillator is used to drive the accumulators to greatly increase the accuracy of the gas gauge functions derived therefrom.

摘要： A high linearity transconductance stage is arranged with a loss cancellation method to remove the nonlinearity of a typical transconductance circuit. The loss cancellation method uses a series of transistors and resistors to supply a controlled feedback current to cancel the result of the change (.DELTA.) in voltage across the input of the transistor used to provide the transconductance for the transconductance stage of a circuit, such as an amplifier, a mixer or other active circuit.

摘要： A variable gain low noise amplifier is disclosed that offers flat gain versus frequency throughout the entire cable and broadcast television signal spectrum. The circuit uses multiple stages and buffering techniques to cancel the primary source of high frequency gain degradation. The invention also uses variable capacitor networks which track with gain control to control peaking within the circuit so as to have consistent gain control with frequency and gain. A further aspect of the invention is in the use of capacitors within the circuit to act as simple band-pass filters to roll off segments of the spectrum away from the channel of interest, thus reducing system-level distortion in a receiver.

摘要： An initializer that responds to change in a power supply potential level, for generating an initialize signal to initialize a circuit to a select state, the initializer includes a power-on reset circuit that switches between an active and a powered-down state, and is for generating the initialize signal. The initializer also includes a wake-up circuit that monitors the power supply potential level and switches the power-on reset circuit from the powered-down state to the active state when selected change in the power supply potential level occurs.

摘要： A comparator which for example can be used for a digital potentiometer is shown. Specifically, a dual differential input circuit with a push/pull amplifier at the output stage is disclosed wherein a crossing is detected in an inputted signal as the crossing occurs and wherein the push/pull amplifier pair at the output stage provides very fast detection of a crossing. This is particularly useful in acting as a trigger mechanism for changes in a digital potentiometer for example to elements noise caused as "wiper changes" occur.
