Frequency Synchronization Circuit Model for Analog Vector-Matrix Multiplication in the Frequency Domain
Taeju Lee, Scott T. Habermehl, Timothy W. Caplice +3
This work introduces a frequency synchronization circuit model for analog vector-matrix multiplication in the frequency domain. The frequency synchronization is implemented by coup…
Oscillation with Negative Impedance
Taeju Lee
Oscillation and frequency modulation have been leveraged for applications in detection (or sensing), data processing, and telemetry. This work provides a theoretical analysis of os…
Analysis of Stability in Multistage Feedforward Operational Transconductance Amplifiers using Successive One-Pole Approximation
Taeju Lee
This paper presents analysis results of the operational transconductance amplifiers (OTAs) that combine feedforward paths and multistage amplifiers to achieve high-gain wideband op…
Noise Analysis for Performance Evaluation of Biopotential Recording Front-Ends
Taeju Lee
Noise efficiency factor (NEF) and power efficiency factor (PEF) are widely used as the figure of merit to quantify the performance of biopotential recording front-ends. NEF and PEF…
