Patent ID: 7202728

Claim:
A signal transmission circuit comprising: a first switch element connecting an input terminal which a start signal or an output signal from a prior stage is input as a first input signal to an output terminal outputting a signal depending on a first control pulse; a first source follower comprising: a gate connected to the output terminal of the first switch element; and a drain to which a second control pulse with a different phase to the first control pulse is supplied; wherein the first source follower outputs a signal to a first output line based on an output signal of the first switch input to the gate; a first capacitor component connected between the gate and the source of the first source follower; a first reference potential fixing circuit comprising; an input terminal to which the first input signal is supplied; and an output terminal connected to a source of the first source follower; wherein the first reference potential fixing circuit fixes a potential of its own output terminal to a reference potential depending on a level of the first input signal; a second switch element which connects an input terminal connected to the source of the first source follower to an output terminal outputting a signal in response to the second control pulse; a second source follower comprising: a gate connected to the output terminal of the second switch element; a drain to which the first control pulse is supplied; and a source supplying an output signal to a subsequent stage and also outputting a signal to a second output line; a second capacitor component connected between the gate and the source of the second source follower; and a second reference potential fixing circuit comprising: an input terminal connected to the source of the first source follower; and an output terminal connected to the source of the second source follower, wherein the second reference potential fixing circuit fixes a potential of the output terminal to a reference potential depending on a level of the input signal from the source of the first source follower.
