Abstract
The present disclosure discloses an input circuit having adaptive voltage-receiving mechanism. A voltage transmission circuit includes an internal N-type transistor and a first N-type transistor. The internal N-type transistor is coupled between an output node for generating an output voltage and a first node. The first N-type transistor is coupled between a first node and a second node and is controlled by a control voltage. The first N-type transistor generates a first node voltage at the first node. The second node is coupled to an input node for receiving an input voltage. A control voltage generation circuit includes a voltage dividing circuit and a first generation circuit. The voltage dividing circuit receives and compares the input voltage to generate a divided voltage. The first generation circuit receives the divided voltage and a supply voltage to generate the control voltage equaling the supply voltage according to the supply voltage being larger than the divided voltage.
