Strategic Objectives
• Master the architecture of ultra-low-power instrumentation amplifiers.
• Minimize thermal and flicker noise in high-precision analog circuits.
• Optimize impedance matching for seamless electrode-tissue interfacing.
• Design robust filtering stages that preserve vital biological data.
The Core Challenge
Capturing millivolt-scale physiological signals is a battle against noise, power constraints, and signal degradation.
