Output Stages

Two new high-performance output stages are proposed. These output stages are basically designed by using a flipped voltage follower (FVF). The proposed low-power and low-voltage output stages have utilized the advantages of the FGMOS technology. They are characterized by low-power dissipation, reduced power supply requirement, and larger bandwidth. By using FGMOS-based FVF in place of conventional FVF, the linearity of the output stages has been highly improved. The small-signal analysis of FGMOS-based FVF is done to show the bandwidth enhancement of conventional FVF. The circuits are simulated to demonstrate the effectiveness using SPICE, in TSMC 0.25-micron CMOS device models. The simulation results show that the power supply requirement of the proposed output stages is highly reduced and bandwidths are extremely higher than the conventional circuits.

This paper presents the design and characterization of a new analog voltage follower for low-voltage applications. The main idea is based on the “Flipped” Voltage Follower and the use of the quasi-floating gate technique for achieving class AB operation. A test cell was simulated and fabricated using a 0,5 μm CMOS technology. When the proposed circuit is supplied with VDD = 1,5 V, it presents a power consumption of only 413 μW. Measurement and experimental results show a gain bandwidth product of 10 MHz and a total harmonic distortion of 1,12 % at 1 MHz.
