This manuscript shows the CMOS design of Lorenz systems using operational transconductance amplifiers (OTAs). Two Lorenz systems are then synchronized in a master?slave topology and used to implement a CMOS secure communication system. The contribution i...

In this paper, we propose a fully standard-cell-based common-mode feedback (CMFB) loop with an explicit voltage reference to improve the CMRR of pseudo-differential standard-cell-based amplifiers and to stabilize the dc output voltage. This latter featur...

This paper presents a novel implementation of a digital-based Operational Transconductance Amplifier (OTA) which has been recently introduced in the technical literature as a fully digital alternative to the conventional differential pair to implement lo...
