Abstract
Apparatuses and methods for mixed charge pumps with voltage regulator circuits is disclosed. An example apparatus comprises a first charge pump circuit configured to provide a first voltage, a second charge pump circuit configured to provide a second voltage, a plurality of coupling circuits configured to voltage couple and current couple the first voltage and the second voltage to a common node to provide a regulated voltage, and a feedback circuit configured to regulate the first voltage and the second voltage based on the regulated voltage.
Claims6
A method for providing charge to capacitive loads comprising:
- activating a first charging applied to first and second electrical components, wherein a first portion of the first charging is applied to the first electrical component and a second portion of the first charging is applied to the second electrical component;
- activating a second charging applied to the second electrical component, wherein the second electrical component is charged to a regulated voltage in response to the second portion of the first charging and a portion of the second charging;
- and
- selectively activating the first and second charging based on a comparison of the regulated voltage to a reference voltage.
