This paper explores a new design approach of a low-power high slew rate CMOS voltage buffer. The buffer is based on the Flipped Voltage Follower Pseudo Differential Pair, but the bulk-driven technique is utilized at the input stage to achieve rail-to-rail operation. This buffer has been designed for a 0.35μm CMOS technology to operate at a 1.8V supply voltage. The BSIM3 simulated results are provided...
This paper describes a rail-to-rail CMOS analog voltage buffer designed to have extremely low static current consumption as well as high current drive capability. The buffer employs a complementary pair of super source followers, but a bulk-driven input device with the replica-biased scheme is utilized to eliminate the DC level shift, quasi-floating gate transistors to achieve class-AB performance,...
A voltage buffer so-called the bulk-driven flipped voltage follower is presented. This proposal is based on the flipped voltage follower (FVF) technique, but a bulk-driven MOSFET with the replica-biased scheme is utilized for the input device to eliminate the DC level shift. The proposed buffer has been designed and simulated with a 0.35 mum CMOS technology. The input current and capacitance of our...
