Precision Feedback Control
Control at the
Speed of Light
FPGA-based closed-loop feedback systems with real-time lock-in amplification and PID control. Sub-microsecond response times for the most demanding precision measurement applications.
ADC Sample Rate
Loop Latency
Resolution
CIC Decimation
Engineered for Precision
Every component of the signal chain is designed for maximum performance and minimum latency.
FPGA-Native Processing
All signal processing runs directly on the Xilinx Zynq FPGA at 125 MHz clock rate. No CPU bottleneck, no OS jitter — deterministic real-time control.
Lock-in Amplification
Multi-tone signal generation with DDS and 6-stage CIC decimation filtering. Extract signals buried deep in noise with configurable bandwidth.
Real-time PID Control
Q16.16 fixed-point PI controller with configurable gains and anti-windup. Closes the loop at up to 1 MSPS after CIC decimation.
Web-Based Control
Real-time oscilloscope display, parameter tuning, and Allan deviation analysis — all from your browser. No proprietary software needed.
Signal Chain Architecture
A complete closed-loop feedback system running at 125 MHz on a single FPGA, with real-time web monitoring and control.
