Abstract:
1. A method for operating a constant current circuit of a buffer circuit that includes an analog buffer circuit and a precharge circuit, wherein a source of a buffer circuit transistor of the analog buffer circuit is a connection point for the constant current circuit, the analog buffer circuit, and the precharge circuit via a switch circuit of the analog buffer circuit, the method comprising: during a first portion of a first time period: during a second portion of the first time period: during a second time period that is subsequent to the first time period: during a precharge period: wherein a full time period comprises a combination of the first time period and the second time period, wherein the precharge period occurs within the full time period, begins at the same time as the first time period, and ends after the second time period begins, and wherein the first time period occurs within the beginning portion of the precharge period.
