School of Engineering Department of Electronic and Computer Engineering 141 An Optofluidic Biological Cell Stretcher Supervisor: POON Andrew Wing On / ECE Student: ZHU Guanhua / CPEG Course: UROP2100, Fall During the last project from UROP1100, we have illustrated the setup of an opto-fluidic single-beam biological cell stretcher, the theory behind the major building blocks of the setup, built the cell stretcher and demonstrated the actual applications of the device. This project focuses on the progress of the last project, including improving the imaging system of the biological cell stretcher, method of processing the images obtained from the imaging system, cell recognition and data extraction from the images using the vision toolbox of MATLAB and the exploration of future works by analyzing the state-of-the-art optical tweezers from other institutions. Circuit Emulation of Bio-Inspired Dynamic and Topological Quantum Systems Supervisor: SHAO Qiming / ECE Student: FU Penglin / SENG Course: UROP1000, Summer In this work, I use electronic components like memristor, MOSFET, op-amp, etc., to simulate a circuit that can perform weighted addition operations. Crossbar structures are used in my work for their space-saving and energy efficiency. Both positive and negative and 0 values of weights are achieved in this work. Also, an approximate activation function can be realized in this work. The training process is not done on this device. Weights and biases are pre-calculated and tuned into the device before usage. By sending input and getting the output of this device, a result the same as a fully connected layer is generated. Circuit Emulation of Bio-Inspired Dynamic and Topological Quantum Systems Supervisor: SHAO Qiming / ECE Student: LIU Yifan / SENG Course: UROP1000, Summer The project should have been designing a practical Operational Amplifier (Op Amp) at first. However, I was not able to figure out everything from scratch due to numbers of problems occurred in the progress. But fortunately, I find the final design of my Op Amp is quite inspiring and I think it could be helpful for beginners to understand how an Op Amp works. Besides, after reading some text books, I think there lack of some simple methods for designing only an Op Amp with MOSFET. Therefore, in this report, although the Op Amp is not practical, it can guide the beginners to design their own Op Amp in a much shorter time. There will be sections around ‘Principle of MOSFET, ‘Optimal Operational Amplifier’, ‘Topology of Op Amp’, ‘Differential Amplifier’, ‘CommonSource Amplifier’, ‘Parallel Resistance’, ‘Class AB follower (In Progress)’ and ‘Verification’.
