摘要:
Circuit embodiments of a multistage voltage regulator circuit are presented, where a circuit includes a first stage that includes a first bias transistor having a current terminal coupled to a first regulated node. The circuit also includes a second stage that includes a second bias transistor having a current terminal coupled to a second regulated node. The circuit also includes a third stage including a third bias transistor having a current terminal coupled to a third node. The circuit also includes a control loop for regulating voltages at the first and second regulated nodes, where the second regulated node is connected to a control terminal of the first bias transistor; and where the first regulated node is connected to a control terminal of the third bias transistor.
