A study of threshold variation compensated inverter-comparator for pulse circuits

This paper studies an inverter-comparator and presents an improved scheme of threshold compensation to enhance the performance of avoiding power supply noise. The inverter can greatly predigest the structure of circuit and save the layout area and depress the power dissipation, so it can be applied in the equipment of moving communications better. It is already proved by simulation with Spectre based on CSMC 0.6/spl mu/m CMOS technical library. There it will be verified with 555 timer and monostable trigger.
