Current mode Schmitt trigger based on ZC-Current Differencing Transconductance Amplifier

A The paper presented here mainly focus on the Current mode Schmitt trigger designed on the basis of ZC-Current Differencing Transconductance Amplifier (ZC-CDTA). The ZC-CDTA used in this proposed circuit is well suited for signal processing applications and biomedical applications. This circuit implementation has been carried out using voltage supply of about ±0.85V and bias current of about 20μA using Cadence and gpdk 180 nm CMOS technology model parameters are used. The Schmitt trigger realized using ZC-CDTA is hermetic to noise, temperature insensitive and high output impedance.
