This paper proposes topological enhancements to increase voltage gain of ultra-low-voltage
(ULV) inverter-based OTAs. The two proposed improvements rely on adoption of composite …

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 …

In this brief we propose a completely novel approach to design robust analog circuits made
up only of digital CMOS gates taken from conventional standard-cell libraries. The approach …

This paper deals with a single-stage single-ended inverter-based Operational
Transconductance Amplifiers (OTA) with improved composite transistors for ultra-low …

This paper presents a calibration-less inverter-based operational transconductance
amplifier (OTA) built with intrinsically matched CMOS inverters, therefore, dispensing any …

In this paper, we propose a novel standard-cell-based OTA architecture based on an
improved version of the differential to single-ended converter, previously proposed by the …

This study presents a new low‐voltage and low‐power, mixed‐mode, universal Gm‐C filter
capable of generating simultaneous filtering outputs. The proposed circuit employs only 19 …

A design solution for bulk-driven tunable transconductor capable of working under extremely
low supply/consumption with rail-to-rail input common-mode range is presented in this work …

A low voltage linear transconductor is introduced. The circuit is a pseudo differential
architecture that operates with±0.2 V supplies and uses 900nA total biasing current. It …

This work presents an Operation Transconductance Amplifier with improved common mode
rejection based in both Nauta's and Vieru's push–pull based OTAs operating at a 0.5 V …
