2001 - IEEE Fellow For contributions to the theory and design of analog adaptive integrated circuits used in digital communications.
The Canadian Academy of Engineering
Electronic engineering, CMOS, Electrical engineering, Adaptive filter and Delta modulation are his primary areas of study. Integrated circuit design is the focus of his Electronic engineering research. The study incorporates disciplines such as Electronic circuit, Comparator and Current mirror in addition to Integrated circuit design.
His CMOS research includes themes of Error detection and correction and Capacitor. His research in Electrical engineering intersects with topics in Dynamic range and Low-power electronics. His study in Delta modulation is interdisciplinary in nature, drawing from both Digital filter, Delta-sigma modulation and Analog signal.
The scientist’s investigation covers issues in Electronic engineering, CMOS, Electrical engineering, Control theory and Delta-sigma modulation. The concepts of his Electronic engineering study are interwoven with issues in Delta modulation, Converters, Operational amplifier and Oversampling. His research links Integrated circuit design with Operational amplifier.
His CMOS research incorporates themes from Capacitive sensing, Sample and hold and Chip. His research investigates the connection between Electrical engineering and topics such as Low-power electronics that intersect with issues in Charge pump. His Control theory research is multidisciplinary, incorporating elements of DC bias and Integrator.
His primary scientific interests are in Electronic engineering, Electrical engineering, Capacitive sensing, Capacitor and CMOS. His Electronic engineering research is multidisciplinary, relying on both Converters, Control theory, Low-power electronics, Switched capacitor and Charge pump. David A. Johns focuses mostly in the field of Low-power electronics, narrowing it down to matters related to Operational amplifier and, in some cases, Signal-to-noise ratio.
He combines subjects such as Power consumption and Navigation system with his study of Electrical engineering. His CMOS research focuses on Topology and how it relates to Electronic circuit, Spurious-free dynamic range, Filter and Topology. His Bandwidth research focuses on subjects like Delta-sigma modulation, which are linked to Oversampling and Noise shaping.
