Z-Copy Current Differencing Buffered Amplifier based Schmitt trigger circuit without passive components
In this paper Z-Copy Current Differencing Buffered Amplifier (ZCCDBA) based new Schmitt trigger is introduced without passive components. This ZCCDBA is a newly introduced active element. It consists of three blocks, namely, Current Differencing Unit (CDU), Voltage Buffer and Third Generation Current Conveyor (CCIII+). The CCIII purpose is to copy the Z terminal voltage and current. The proposed Schmitt trigger consists of a single ZCCDBA block without passive components. This type of configuration helps and suits for IC implementation. The proposed circuit was simulated under ±0.8 V supply voltage with the bias currents such as IB1 = IB2 = 60 µA and IB3 = 10 µA using Cadence tool and with model parameters of gpdk 180 nm technology.
