A Novel Dual Output Schmitt Trigger Using Second Generation Current Controlled Conveyor

Abstract

Schmitt trigger is designed using the single second
generation Current Controlled Conveyor. The proposed
configuration utilizes single CCCII and only two externally
connected resistors and is able to produce dual output square
wave signal. The topology has the benefit of having a simple
circuit, offering a large bandwidth and improved slew rate.
PSPICE simulator using OrCad 16.3 version, 0.35 μm CMOS
technology is used to verify the design, hysteresis is determined
and compared with the existing methods available in the
literature. The proposed configuration is tested using the
experimental setup involving CFOA (AD844AN) and OTA
(LM13700). The results have been found satisfactory in both
simulation and experimental aspect. Montecarlo analysis and
worstcase analysis are determined to prove the circuit efficiency
in terms of critical parameters such as resistance with a tolerance
of 5%. The hysteresis is also determined, that can reduce the
effect of noise, able to produce exact square wave at the output.
Schmitt trigger circuits find the applications in the field of Bio
medical applications, analog signal processing, communication
systems, waveform generators, pulse width modulators,
multivibrators, flip-flops and in many other amplifier circuits.
The basic application of Schmitt trigger is a square wave
generator. The proposed topology is the best suited for
monolithic IC fabrication.
