| Our project aims to create faster and more efficient wireless communication systems by developing a 60GHz RF receiver consisting of a Mixer, Voltage Control Oscillator (VCO), and a Low Noise Amplifier (LNA). The unlicensed 60GHz band presents an opportunity for research and development, benefiting industries such as telecommunications, autonomous vehicles, and other emerging technologies. |

| Our team is building a fully integrated switch mode power supply, similar to the ones on the JLab benches, that supports Channel A (1V-20V, 0A-3A), Channel B (1V-20V, 0A-3A), and Channel C (5V, 3A). Channel A & B can be connected in independent, parallel, or series modes. Channel C supports USB-C slow charging over USB 2.0. The generic block diagram is rectifier, fly back transformer, protection circuit, feed back, and output enable. |

| Power is an increasingly important field in the world of today's technology. With the rise in importance for high-power DC-DC converters in applications such as data centers, low-load devices are often underresearched - proven by the low efficiency of conventional buck-boost converters at low load. This project aims to implement a DC-DC buck-boost converter, which remains relatively efficient at low loads, via the use of innovative modulation techniques such as PSM, PFM, and PWM. |

| BeamSeek is a novel Direction of Arrival (DOA) estimation method for millimeter-wave phased arrays with low-complexity hardware implementations. Rapid, accurate, pilot-free DOA estimation is achieved by combining agile beam switching with a neural network. BeamSeek was trained using an iterative training approach that incorporated physics-informed data augmentation and was tested on the NSF PAWR COSMOS testbed at 60 GHz. BeamSeek reduced the average estimation error by up to 8 degrees, and demonstrated particular advantages in noisy channels. |
