A pipelined analog-to-digital converter with low-gain, low-bandwidth op-amps
… this thesis presents the shadow-ADC-assisted digital calibration technique. The proposed technique relaxes op-amp performance requirements by removing op-amp-induced charge-transfer errors in the digital domain. A proof-of-concept pipelined ADC has been designed in 28nm FDSOI CMOS technology …

Analog Signal Processing Elements for Energy-Constrained Platforms
… direct application in the analog as well as the digital domain. Indeed, research shows that as the resolution of a signal processor falls below a system-dependent threshold, it is almost always more efficient to preform the processing in the analog domain. These continuous-time circuits have long …

A cross-platform virtual reality experience
… cross-platform observation and agency within the digital domain. Namely, this new form of human-to-human virtual interaction method allows two or more individuals to simultaneously observe and interact with the same virtual world through inherently different perspectives. More specifically, this …
