Weidong Wang · Dianzi qijian · 2011
A novel CMOS differential voltage current conveyor based on a wide linear range transconductor with common mode detection was designed.The proposed circuit consists of long tail differential pair with dynamic tail current.The proposed DVCCⅡ has exact voltage following performance and wide range input voltage.The circuit has low voltage and low power than any other circuits.Using SMIC 0.18 μm CMOS technology the supply voltages is 0.9 V.It consumes the power of 1.4 mW.The novel DVCCⅡ is used to realize an instrumentation amplifier and a multifunction filter.
