Abstract
In this paper, a novel high-bandwidth and low-power buffer amplifier is
presented for the liquid crystal display applications. This buffer amplifier
consists of a folded cascade differential amplifier in the input and a
class-amplifier in the output, which are designed carefully. The proposed
buffer amplifier utilizes a high-performance feedback circuit to increase the
bandwidth. It also utilizes a comparator circuit to avoid wasting power. The
designed circuit has been simulated in 180nm technology using HSPICE 2008.3.
The simulation results show that the bandwidth, power consumption and power
supply of the designed circuit are 1.14MHz, 1.64mW and 1.8V, respectively.
