Design and develop accurate signal conditioning chains, signal converters, sampling systems, and drivers for high precision measurement instruments, including analog front-end solutions.
Responsibilities
- Architect analog front-end (AFE) solutions for sensor interfacing covering thermocouples, RTDs, strain gauges, photodiodes, electrochemical cells, and other transducers
- Perform detailed analog signal chain analysis including noise budgeting, bandwidth optimization, dynamic range assessment, and distortion characterization
- Select and evaluate critical components (op-amps, ADCs, DACs, voltage references, analog switches, multiplexers) based on performance, cost, and supply chain considerations
- Design and implement high-resolution ADC and DAC subsystems (SAR, Sigma-Delta, pipelined) with careful attention to grounding, shielding, and clock distribution
- Develop low-noise, low-ripple power supply architectures tailored for sensitive analog circuits with detailed power budget and noise control
Requirements
