Abstract: A bootstrapped switch circuit coupled to a timing circuit. The bootstrapped switch circuit comprises a charge pump coupled to the timing circuit. The bootstrapped switch circuit also comprises a logic circuit coupled to the output of the charge pump and the timing circuit. The logic circuit is capable of generating multiple control signals which can independently control the turn-on of switches in the voltage path between the inputs and outputs of the bootstrapped switch circuit.

Abstract: Techniques are described through which continuous gapless voltage measurements can be synchronized between devices with independent clock sources on an asynchronous bus by slightly adjusting a speed of a local clock source for a period of time. Also, a read-out technique is described through which the synchronous measurements can be read out in a coherent way. These techniques can allow a high-accuracy time-average of the battery cell voltage (or fuel cell voltage) to be reconstructed, while allowing the same results to be synchronous across an entire battery stack, for use in instantaneous voltage/current diagnostics or calculations.

Abstract: A charge pump is connected between a source and a body of the switch. Such a configuration avoids a condition in which the body diode opens for negative drain-to-source voltage (Vds) across the switch. Such a configuration also avoids a condition in which the switch control circuit generates control signals referenced to a body potential rather than a source potential, thereby allowing the switch to reliably turn off even for negative Vds. An additional gain stage ensures that the switch can be properly turned on. The techniques can be used to generate switches that enable highly linear processing of bipolar differential signals even far outside of the supply range.

Abstract: A system for reducing a voltage-dependent effect of a first capacitor caused by a first voltage may include the first capacitor, which may include a first physical spacing between a first capacitor terminal conductor of the first capacitor and a second capacitor terminal conductor of the first capacitor. The system may also include a second capacitor, which may include a second physical spacing between a first capacitor terminal conductor of the second capacitor and a second capacitor terminal conductor of the second capacitor, where the second physical spacing is different from the first physical spacing. The system may also include a compensation circuit, which may be arranged to receive and at least partially offset a voltage dependent signal contribution from each of the first and second capacitors for output to a signal-processing circuit.
