摘要： This document discusses, among other things, a regulator circuit. The regulator circuit can controllably connect a first voltage to an inductor using a first switch and can controllably connect a second voltage to the inductor using a second switch. The first switch can be turned off and the second switch can be turned on for a duration proportional to a difference between the first voltage and a third voltage, divided by the first voltage. The first switch can be turned off and the second switch can be turned on for a duration proportional to the third voltage divided by the first voltage. One of the first or third voltages can correspond to a desired output voltage.

摘要： An auto-zeroing, high impedance buffer for a sample and hold module that draws substantially no current from the input and has substantially no offset voltage at the output is discussed. During a hold mode, the offset voltage of an op-amp is accumulated on a capacitor. When the sample operation ensues the input signal is directed to the op-amp input via the capacitor where the circuitry is arranged so that the offset on the capacitor cancels the offset voltage of the op-amp. A second circuit may be fashioned and input to a sample and hold circuit for full differential operation.

摘要翻译： 讨论了用于采样和保持模块的自动归零高阻抗缓冲器，其基本上不从输入端抽取电流，并且在输出端基本上没有偏移电压。 在保持模式期间，运算放大器的偏移电压累积在电容器上。 当采样操作接着输入信号通过电路布置在电容器上的运算放大器输入端时，电容器的偏移消除了运算放大器的偏移电压。 可以形成第二电路并将其输入到采样和保持电路以进行全差分操作。
