In the last years several ultra-low voltage (ULV) operational transconductance amplifiers (OTAs) with supply voltages below 0.5V have been proposed in the literature. To achieve high gain, multi-stage amplifiers are frequently exploited, in spite of

In this paper we introduce an improved standard-cell-based voltage amplifier cell with low output resistance. The proposed amplifier cell exhibits a voltage gain whose value can be accurately set by the number of paralleled inverters, and its output

In this paper a novel ultra-low voltage (ULV) standard-cell-based comparator which provides rail-to-rail input common-mode range (ICMR) is presented. The topology, unlike the others in the literature, uses only 2-inputs NAND gates and is able to oper

An approach to design analog building blocks based on digital standard cells is presented in this work. By ensuring that every CMOS inverter from a standard-cell library operates with a well-defined quiescent current and output voltage, the suggested

This work is focused on the performance of three different standard-cell-based comparator topologies, considering ultra-low-voltage (ULV) operation. The main application scenarios in which standard-cell-based comparators can be exploited are consider

In this paper, we present a 0.3 V body-driven operational transconductance amplifier (OTA) that exploits a biasing approach based on the use of a replica loop with gain. An auxiliary amplifier is exploited both in the current mirror load of the first

This paper presents a novel Strong Arm comparator in which the input pair is reused as a static amplifier to preamplify the input signal during the precharge phase. The proposed approach relaxes the main trade-offs that characterize the Strong Arm la

This paper presents a novel 0.3V rail-to-rail body-driven three-stage operational transconductance amplifier (OTA). The proposed OTA architecture allows achieving high DC gain in spite of the bulk-driven input. This is due to the doubled body transco

For the design of inverter-based OTAs with differential input and single-ended output, the differential to single-ended (D2S) converter is a key building block. In fact, the performance of the D2S strongly affects the overall common-mode rejection ra
