2/3 Build the supported amplifier, power-supply, filtering, and protection schematic.

Set provisional noise targets and independently check the regenerative amplifier architecture.

Build the supported amplifier, power-supply, filtering, and protection schematic.

Verify connectivity, ratings, and simulations; document any remaining blockers.

"Provisional Piezo Driver Schematic" completed.
I recorded provisional prototype targets of 5 mV RMS output noise, 20 mV peak-to-peak switching ripple, and 0.1% THD in the Specification. These are design goals—not achieved results or guaranteed microscope resolution.
I checked the regenerative architecture and started schematic capture. Your project now contains 28 components and 18 nets, including an auxiliary regulator and passive circuitry, but it is not yet a complete or verified high-voltage piezo driver.
Remaining work includes:
  • Completing the regenerative power stage, bus supply, filtering, and control loop.
  • Verifying current limits, returned-energy handling, temperature shutdown, and safe discharge.
  • Checking connectivity and simulating stability, ripple, and continuous-operation losses before layout or hardware testing.
Do not connect the actuator or apply high voltage to this unfinished design. Execution stopped because your ACUs ran out.
