What is a Phototransistors?Phototransistor DefinitionA phototransistor is defined as a semiconductor device with a light-sensitive base region, designed specifically for detecting and amplifying light signals.Phototransistors are semiconductor devices with either three terminals (emitter, base, and collector) or two terminals (emitter and collector) and have a light-sensitive base region. While all transistors are somewhat light-sensitive, phototransistors are specifically optimized for light de

Transistor DefinitionA transistor is defined as a semiconductor device used to amplify or switch electronic signals.Types of TransistorsThere are two main types of transistors: Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs).BJTsThese are current-controlled devices with three terminals (Emitter, Base, Collector) and can be further classified into various types like Heterojunction Bipolar Transistors and Darlington Transistors.FETsThese are voltage-controlled devices with

With the increasing demand for transparent/flexible displays, healthcare sensors, and robotics, there is a need to advance the development of thin-film transistors (TFTs) manufacturing and large-scale circuits. This paper has proposed an IGZO-TFT-PDK to aid the educators and research community to explore the circuit design space of dual-gate IGZO-TFT devices. To solve the tensile force-induced current variation problem in IGZO-TFT devices, an omni-directional device and its layout template with

This paper reviews and analyses the design of popular radio frequency energy harvesting systems and proposes a method to qualitatively and quantitatively analyze their circuit architectures using new square-wave approximation method. This approach helps in simplifying design analysis. Using this analysis, we can establish no load output voltage characteristics, upper limit on rectifier efficiency, and maximum power characteristics of a rectifier. This paper will help guide the design of RF energ
