Abstract
A rail-to-rail input stage circuit including a first P-type transistor, a second P-type transistor, a first N-type transistor, a second N-type transistor, a first processing circuit, a second processing circuit, a first voltage adjustment circuit, and a second voltage adjustment circuit is provided. The first P-type transistor and the first N-type transistor are coupled to a first input terminal. The second P-type transistor and the second N-type transistor are coupled to a second input terminal. In response to the voltage of the first terminal being higher than a first threshold value, the first voltage adjustment circuit controls the operation of the first processing circuit. In response to the voltage of the first terminal being lower than a second threshold value, the second voltage adjustment circuit controls the operation of the second processing circuit.
