A Bulk Driven Transimpedance Cmos Amplifier For Sipm Based Detection, Shahram Hatefi Hesari
A Bulk Driven Transimpedance Cmos Amplifier For Sipm Based Detection, Shahram Hatefi Hesari
Masters Theses
The contribution of this work lies in the development of a bulk driven operational
transconducctance amplifier which can be integrated with other analog circuits and
photodetectors in the same chip for compactness, miniaturization and reducing the
power. Silicon photomultipliers, also known as SiPMs, when coupled with scintillator materials are used in many imaging applications including nuclear detection. This thesis discuss the design of a bulk-driven transimpedance amplifier suitable for detectors where the front end is a SiPM. The amplifier was design and fabricated in a standard standard CMOS process and is suitable for integration with CMOS based SiPMs and commercially …
Design Of A Bandgap Voltage Reference, Nicolaus Vail
Design Of A Bandgap Voltage Reference, Nicolaus Vail
Electrical Engineering Undergraduate Honors Theses
This thesis details the design process of a bandgap voltage reference (BGR) integrated circuit in a 180 nm CMOS process. A BGR provides a constant DC voltage across a range of operating temperatures and supply voltages. By its nature, the circuit is intended as a reference, not to provide current, so the output would be connected to a very high impedance, such as the gate of a transistor. At 27°C, this design provides a 955 mV reference voltage given a nominal VDD of 3 V. From 20°C to 175°C, the output voltage has a variance of 7.2 mV (approximately 0.8%) …

Automatic Gain Control Integrated Circuit, Kyman Huang, Garth Leung, Lauren Williams
Electrical Engineering
This paper aims to describe the design process of an automatic gain controller (AGC) integrated circuit. An AGC is intended to provide variable gain in order to produce a consistent, distortionless output with a wide range of input magnitudes. This implementation was created as a standalone, small IC for audio systems. The chip requires only 7 pins, allowing for a small 8-pin package. LTSpice was used for the circuit design process and initial simulation. Cadence Virtuoso was used for the circuit layout and further simulations. Xilinx Vivado was used for digital circuit design and initial simulations. This project set out …
Dual Channel Matrix Switch Audio Receiver, Austin Fox
Dual Channel Matrix Switch Audio Receiver, Austin Fox
Electrical Engineering
The Dual Channel Matrix Switch Audio Receiver controls 2 separate audio output channels. Each channel plays any of the system's 3 inputs. This controller enables a user to play two separate audio signals through two separate speaker channels. The system design allows audio input from 2 RCA sources or 1 RCA source and a phono source. The system outputs an audio signal for each output simultaneously at up to 36W on each channel for an 8Ω load. The device allows a user to control the audio input and the volume of each output channel. An Arduino Uno R3 microcontroller interfaced …
