⭐⭐⭐⭐⭐ Designing a power supply for a radio mixed-signal system isn’t just about regulation — it’s about noise control, rail isolation, and clean layout strategy so the RF section performs properly. I have experience designing multi-rail power architectures for analog + digital systems, including switching pre-regulation followed by low-noise LDO stages for RF-sensitive domains. I use SPICE-based simulation to validate ripple, load transients, and stability before hardware. Proposed workflow: Milestone 1 – Define input range + required rails (voltage/current/noise targets) Milestone 2 – Architecture selection (buck/boost + LDO strategy + filtering) Milestone 3 – SPICE simulation (ripple, startup, transient response) Milestone 4 – Schematic + component selection (low-noise, available parts) Milestone 5 – Layout guidance notes for mixed-signal grounding and EMI control Quick questions: • What are the required output rails and current levels? • Is there a high-power RF PA involved? • Size/efficiency constraints? I’m happy to share examples of mixed-signal power designs and simulation results upon request.
