Title:
LOW VOLTAGE CHARGE TRANSFER CIRCUIT USING NEGATIVE VOLTAGE AND GATE VOLTAGE BOOTSTRAPPING
Document Type and Number:
WIPO Patent Application WO/2019/242396
Kind Code:
A1
Abstract:
A low voltage charge transfer circuit using negative voltage and gate voltage bootstrapping, comprising a charge transfer MOSFET (S), a gate voltage bootstrap boost circuit, a negative voltage transfer MOSFET (B), a voltage switch (K), a negative voltage production circuit, a positive and negative voltage clock production circuit, a first NMOS transistor (M1), a second NMOS transistor (M2), a PMOS transistor (M3), a first capacitor (C1), and a second capacitor (C2). The present circuit overcomes the problem of limited signal swing in existing signal transmission circuits, and can be widely used in various types of signal processing circuits.
