Hi, I'm Ashley Rivera

Electrical Engineer and Hobbyist Musician

Hello!

I'm Ashley, an aspiring circuit design engineer and recent electrical engineering graduate from the University of Toronto. During my undergraduate studies, I specialized in analog/digital electronics, semiconductor physics, and obtained a certificate in music technology.

I was drawn to circuit design after learning about the theory and implementation of low-pass, high-pass, and bandpass filters. I was initially introduced to these three concepts while producing music as a teenager. Learning about how these filters actually worked piqued my interest in circuit design, and the rest is history.

I am always looking for new ways to innovate within the semiconductor industry, and am particularly keen on exploring circuit design for quantum computing and photonics applications.

Past Projects

160 GBaud 2x Time Interleaved ADC Front-End

A 1:2 analog demultiplexer capable of operating at a symbol rate of 160 GBaud/s with an SNDR of 42 dB, an energy-to-bit efficiency of 0.15 pJ/bit, and a power consumption of 47 mW.

Designed and fabricated using GlobalFoundries' 22nm FDSOI process.

Light-Based Theremin

A two-part analog circuit that resembles a theremin, a musical instrument played by waving your hands. The design consists of an oscillator (square wave generator) and an additional amplifier for master volume control. Served as the foundation for the ECE231 and ECE360 op-amp labs at the University of Toronto.

The Harmonizer

Hardware project built using an Arduino hooked up to an LCD display and a speaker. Randomly generates a chord progression, geared towards musicians who aim to develop their improvisational skills. This serves as my introduction to Arduino and working with embedded systems.
