Multistage amplifiers are a reliable method of achieving high gain in systems where the voltage supply is low. The common practice to prefer 3-stage over 4-stage ones when <;120 dB required, since former easier compensate. In this article, we employ four stages relax constraints on each stage. An extension single Miller-capacitor compensation and active-parallel operational transconductance amplifier (OTA) design work capable driving capacitor range 400 pF 12 nF(30×) by consuming total power...

Since operational transconductance amplifiers (OTAs) form the basic building blocks of many analog systems, compensation three-stage OTAs has attracted a lot attention in literature. Many different solutions to stability problem such have been proposed over past 20 years, with each solution exhibiting properties or targeting application. This work surveys broad selection previously reported architectures and proposes novel classification scheme that exposes features common seemingly serves...

With the aggressive scaling of transistor dimensions, intrinsic device gains are dropping but need for high-gain amplifiers still exists, resulting in a great interest multistage amplifiers. Most existing amplifier topologies rely on Miller capacitors which achieve stability at expense reduced speed. In this paper, new state feedback compensation strategy with gain enhancement using partial positive is proposed whereby can be made output-compensated, thereby requiring no capacitance while...

Integrating multiple on-chip voltage regulators in a power delivery network (PDN) can offer promising improvements both regulation and efficiency. However, the complex interactions between active surrounding parasitic passive create large number of feedback loops thus cause stability concern for distributed network. The recently emerged PDN design methodology based on hybrid theory (HST) provides unique opportunity taming problem. HST-based margin is unfamiliar to circuit designers,...

Fully differential amplifiers require the use of common-mode feedback (CMFB) circuits to properly set amplifier’s operating point. Due scaling trends in CMOS technology, modern increasingly rely on cascading more than two stages achieve sufficient gain. With multiple gain stages, different topologies for implementing CMFB are possible, whether using a single loop or ones. However, impact performance each approach has seldom been studied literature. The aim this work is guide choice...

With the growing performance and wide application of deep neural networks (DNNs), recent years have seen enormous efforts on DNN accelerator hardware design for platforms from mobile devices to data centers.

Systolic array-based datacenter applications high power consumption nonuniform workload distribution, which makes delivery network...

A major challenge currently facing integrated systems, such as microprocessors and systems-on-chip is power delivery. With increasing system size complexity, multiple voltage regulators are often needed for a single domain. This connection raises non-trivial stability issues that render the useless.

Large-scale systems-on-a-chips (SoCs) have stringent power requirements to ensure adequate supply of on-die devices and prevent catastrophic timing violations. Heterogeneous voltage regulation (HVR) leveraging a combination on-chip off-chip regulators has been advocated for ensuring integrity with maximum efficiency. However, unavoidable process temperature variations not considered in prior HVR work. In this paper, we present an in-depth evaluation the impacts on HVR. Furthermore, propose...
