Class-ab Rail-to-rail Cmos Buffer Amplifier for Tft-lcd Source Drivers

A class-AB rail-to-rail CMOS buffer amplifier is proposed and fabricated. The main circuit structure includes a bias circuit, a complementary folded-cascode differential input stage, a common-mode rejection ratio (CMRR) enhancement stage, and a class-AB output stage. With the complementary folded-cascode input stage, high input common-mode range (ICMR) and rail-to-rail output are realized. By u...

An Ultra Low-Power High-Speed Rail-to-Rail Buffer Amplifier for LCD Source Drivers

An ultra low-power high-speed rail-to-rail buffer amplifier with improved current summing circuit is proposed for LCD source drivers. By placing two complementary differential pairs in parallel, it is possible to obtain a rail-to-rail input stage. Then, a current summing circuit with two embedded comparators is proposed. With the proposed current summing circuit, the output stages will be turne...

A Rail-to-rail High Speed Class-ab Cmos Buffer with Low Power and Enhanced Slew Rate

A rail-to-rail class-AB CMOS buffer is proposed in this paper to drive large capacitive loads. A new technique is used to reduce the leakage power of class-AB CMOS buffer circuits without affecting dynamic power dissipation .The name of applied technique is LECTOR, which gives the high speed buffer with the reduced low power dissipation (1.05%) and reduced area (2.8%). The proposed buffer is si...

A Low-Power 900 mV Rail-to-Rail Class-AB Operational Amplifier

In this paper, we proposed a novel rail-to-rail CMOS opamp that uses a native NMOS input stage 10 replace conventional PMOS pair. A simple current regulation circuit, which takes advantage of weak inversion mode, is proposed to obtain constant Gm in the entire common mode range. In addition, a classdB outpuf buffer, which consists of twofloat currenf sources, is employed to obtain a wide output...

A Low Voltage, Rail-to-Rail, Class AB CMOS Amplifier With High Drive and Low Output Impedance Characteristics

This paper describes a CMOS rail-to-rail class AB operational amplifier designed to have extremely low output impedance and large current-drive capability. The amplifier uses an innovative output stage, having both source follower and common source stages working simultaneously throughout the output common-mode range. The source follower ensures low output impedance, which enables it to drive r...
