HARDWARE
Here are some of the hardware projects I have designed, manufactured, and tested throughout my college career!
01
Electrocardiogram Circuit
This PCB reads electrical heart signals and displays them on an oscilloscope. It consisted of a power supply, anti-aliasing filter, instrumentation amplifier, and an isolator.
02
Audio Visualizer
This circuit used a 9V battery power supply to amplify an audio-jack sound signal which was then frequency - separated by two Butterworth filters. Finally, a MOSFET-based current driver used these outputs to light up the LEDs at the rhythm of the song.
03
Microwave/RF Components
Designed, fabricated, and tested a total of 7 microwave/wireless circuits: a quadrature coupler, a Wilkinson power-divider, bandpass filter, phase-shifter, two types of low-pass filters, and a patch antenna.
04
Low-Dropout Voltage Regulator Design
Designed an LDO with a basic two-stage OP-AMP configuration. Made use of a differential amplifier followed by a PMOS source-follower. Also applied Miller Capacitance calculations to stabilize the poles generated by parasitic capacitors.
