Abstract

In this study, a new ultra-low voltage
and ultra-low power voltage differencing buffered amplifier (VDBA) based on
dynamic threshold voltage MOS transistors (DTMOS) is proposed. A voltage mode
filter configuration is also presented as an application for the proposed VDBA.
This filter employed two VDBA blocks and two passive components. The total power
consumption of VDBA block is found simply 6.22 nW at a 0.4 V supply voltage. The
simulation results by using LTSpice Program with 0.18 μm TSMC CMOS technology
model parameters are carried out to show the performance of the proposed active
device and its filter applications.
