Abstract :
A current-mode electronically-tunable Schmitt Trigger circuit is presented. The analog building block used is a new Multiple-Output CDTA (MO-CDTA) which is designed and implemented at 65 nm CMOS technology node. The proposed circuit employs only a single MO-CDTA and no passive components thereby making it attractive for integration. The operation of the proposed Schmitt Trigger was verified by using SPICE simulations. Electronic tunability of the hysteresis characteristics was also explored with good results. A simple application of the proposed Schmitt Trigger, in the form of a current-mode clock generator is also presented.
