Abstract
A voltage divider circuit arrangement includes a resistive divider circuit portion constructed from first and second resistors (R1, R2) The first and second resistors are connected in series and are arranged to provide a refresh voltage (Vrefresh) at a refresh node between them. A capacitive divider circuit portion is constructed from first and second capacitors (C1, C2). The first and second capacitors are connected in series and are arranged to provide an output voltage (Vout) at an output node. A switching circuit portion is arranged intermittently to switch the voltage divider circuit arrangement between a first mode wherein the resistive divider is enabled and the output node is connected to the refresh node, and a second mode wherein the resistive divider is disabled and the output node is not connected to the refresh node.
