Abstract
The present disclosure provides a buffer circuit and a buffer. The buffer circuit includes: an input follower circuit for following the voltage change of the first input signal; an input follower linearity boosting circuit for improving follower linearity of the input follower circuit; a first voltage bootstrap circuit for bootstrapping the voltage of the first input signal; a second voltage bootstrap circuit for bootstrapping the voltage of the second input signal; a third voltage bootstrap circuit for providing corresponding quiescent operation point voltage; a compensation follower circuit for following the compensation voltage; a compensation follower linearity boosting circuit for improving follower linearity of the compensation follower circuit; a first load for collecting the buffered voltage; a bias circuit for providing a bias current for the buffer; a bias linearity boosting circuit for improving linearity of the bias circuit; a second load for generating a nonlinear compensation current.
