Property degree input signal buffer of micro-power wireless communication chip

The invention discloses a property degree input signal buffer of a micro-power wireless communication chip. The property degree input signal buffer comprises an input driving circuit and a following holding circuit, the input drive circuit is characterized in that the input drive circuit is of a source electrode following structure, and the nonlinearity of an NMOS source electrode follower is reduced through a linearization enhancement technology; the following holding circuit is mainly switched among three phases of a reset sampling capacitor, an input following phase and a margin amplifyingphase. The invention discloses the property degree input signal buffer of the micro-power wireless communication chip. Through the plurality of auxiliary source follower circuits, the amplitude of the change of the relative voltage between the ports of the input tube of the main source follower along with the change of the input signal and the relative static voltage difference are reduced, and the linearity of the main s
