Abstract

In this paper we present new construction of CMOS current conveyor based self cascode current mirrors used in tunable band pass filter. Thus the first step in our design was to improve the CCII performance characteristic. The low voltage self cascode technique in CMOS technology was first studied. A tunable current- mode band pass filter using active elements unity gain current conveyor based self cascode current mirror is presented. The Q-factor and the central frequency can be electronically controlled by a DC bias current. To verify this, a Pspice simulations were carried out using 0.7 um technology CMOS process from AMIS.
