Buffer circuit with regulating function and regulating circuit thereof
A regulating circuit is used with a buffer circuit. The buffer circuit at least includes a metal-oxide-semiconductor transistor and a voltage output terminal. The voltage output terminal is connected to a drain terminal of the metal-oxide-semiconductor transistor of the buffer circuit. The regulating circuit includes a first metal-oxide-semiconductor transistor and a second metal-oxide-semiconductor transistor. The first metal-oxide-semiconductor transistor has a source terminal and a drain terminal connected to a voltage source and a connecting node, respectively. The connecting node is electrically connected to a substrate of the metal-oxide-semiconductor transistor of the buffer circuit. The second metal-oxide-semiconductor transistor has a drain terminal and a source terminal connected to the connecting node and the voltage output terminal, respectively. A substrate of the second metal-oxide-semiconductor transistor is electrically connected to the connecting node.
