Abstract
The present disclosure provides an induction amplifier circuit, a control method thereof and a preparation method thereof, wherein the induction amplifier circuit comprises: an induction amplifier electrically connected to a storage unit of a semiconductor memory; and a preamplifier between the induction amplifier and the storage unit, the preamplifier being configured to pre-amplify an electrical signal from the storage unit to the induction amplifier. Further, by arranging the preamplifier between the induction amplifier and the storage unit, the stored electrical signal in the semiconductor memory can be output after two-stage amplification by the preamplifier and the induction amplifier, thereby avoiding the problem that when the induction margin of the induction amplifier signal is small, the electrical signal output by the storage unit cannot be accurately received and output.
