This repository contains the code, design files, and documentation for a university project focused on creating a common emitter BJT amplifier using Proteus simulation software with PCB Implementaion ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

An Amplifier is an electronic circuit designed to increase the strength of a weak input signal in terms of voltage, current, or power. This process is called Amplification. Couples the AC signal to ...

Abstract: This paper proposes a germanium-silicon integrated low-noise amplifier based on an AC-coupled common-emitter topology by simulation. The circuit structure adopts a cascaded dual-bias circuit ...

Abstract: The effects of packaging on the performance of inductively degenerated common-emitter low-noise amplifiers (LNAs) are examined and the equations describing the input impedance, ...

Figure 1 The addition of a simple diode in the emitter circuit yields the symmetric waveform in Figure 4. Figure 2 This amplifier circuit produces the distorted waveform in Figure 3. Diode D 1 ...

This applications note presents some basic facts about phototransistors including its different architectures commonly used in the industry. It discusses its operation and how things work inside these ...
