Schmitt Trigger based on Dual Output Current Controlled Current Conveyor in 16nm CMOS technology for digital applications

Abstract

This paper presents a current mode Schmitt Trigger based on Dual Output Current Controlled Current Conveyor (DOCCCII). To overcome the frequency limitation and enable low voltage low power operation (LVLP) current mode circuits are generally preferred. They offer higher bandwidth, improved slew rate and better (LVLP) performance compared to their voltage mode counterparts. So for the design we have selected second generation current controlled current conveyor which is regarded as the universal current mode active building block. The circuit topology is very simple, its construction consists of a single DOCCCII and an inverter implemented in 16 nm bulk CMOS technology model parameters obtained from Predictive Technology Model (PTM) together with two resistors. The circuit is suitable for integration, it uses the supply voltage of ±0.8V and a bias current of 10μA. The performance of the proposed circuit is examined using H-Spice where the circuit exhibited the power dissipation of 57.78μW. The circuit performance is in agreement with the theoretical explanation. The noise removing capability of the circuit is presented here as an application.
