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%) …
Design And Fabrication Of A Microstrip Bandpass Filter In Ltcc, Allison Rucker
Design And Fabrication Of A Microstrip Bandpass Filter In Ltcc, Allison Rucker
Electrical Engineering Undergraduate Honors Theses
The goal of the project was to design and fabricate a bandpass filter with a center frequency of 25GHz with a 2GHz bandwidth. The first step was to do the calculation to design a bandpass filter to meet these specifications along with the properties of the DupontTM GreenTapeTM 9K7. HFSS was then used to verify the results from the initial calculations. There was a significant error between the two results, so more tweaking was done to the calculations to get a better center frequency. After a final design was decided, the fabrication process started. Low-Temperature Co-Fired Ceramics (LLTC) …
Design Of A Folded Cascode Operational Amplifier In A 1.2 Micron Silicon-Carbide Cmos Process, Kyle Addington
Design Of A Folded Cascode Operational Amplifier In A 1.2 Micron Silicon-Carbide Cmos Process, Kyle Addington
Electrical Engineering Undergraduate Honors Theses
This thesis covers the design of a Folded Cascode CMOS Operational Amplifier (Op-Amp) in Raytheon’s 1.2-micron Silicon Carbide (SiC) process. The use of silicon-carbide as a material for integrated circuits (ICs) is gaining popularity due to its ability to function at high temperatures outside the range of typical silicon ICs. The goal of this design was to create an operational amplifier suitable for use in a high temperature analog-to-digital converter application. The amplifier has been designed to have a DC gain of 50dB, a phase margin of 50 degrees, and a bandwidth of 2 MHz. The circuit’s application includes input …
