- Audio & low-noise PCB
- Analog signal conditioning
- Op-amp & instrumentation amplifier
- ADC/DAC & codec integration
- Active/passive filters
- Microphone & headphone preamp
- Audio mixer & audio interface
- Sensor signal conditioning
- Analog front-end & measurement circuits
- Bluetooth audio hardware
- Schematic, PCB layout, BOM & Gerber files
SOFTWARE
KiCad, Altium Designer, EasyEDA, LTspice and other professional engineering tools.
WHY CHOOSE ME
- Pro circuit-focused approach
- Clean, practical PCB design
- Attention to signal paths, grounding and noise
- Manufacturing-ready documentation
- Clear communication and project guidance

Yes. I can design amplifier PCBs based on your required power, supply voltage, load impedance, input signal and application.
Do you design Class A, Class AB and Class D amplifiers?
Yes, I can work on Class A, Class AB and Class D amplifier designs depending on your project requirements.
Can you design a preamplifier or microphone preamp?
Yes. I can design preamp circuits for microphones, audio sources and other low-level signals.
Can you work on low-noise analog circuits?
Yes. I consider signal routing, grounding, filtering, component selection and other design factors relevant to reducing unwanted noise.
Can you design signal-conditioning circuits?
Yes. I can design amplification, filtering and conditioning stages for audio, sensors and measurement applications.
Can you integrate ADC and DAC components?
Yes. I can integrate ADC/DAC devices with the required analog signal-conditioning and interface circuitry.
Can you design an audio mixer or audio interface PCB?
Yes. I can design the required analog signal paths, interfaces and PCB according to your specifications.
Do you provide Gerber, BOM and schematic files?
Yes. Deliverables depend on the package selected and can include schematic, BOM, Gerbers, drill files, source files and 3D PCB files.
Can you review or improve my existing PCB design?
Yes. Send your existing schematic, PCB files and requirements so I can review the design and identify areas that may need improvement.
Should I contact you before placing an order?
Yes, kindly inbox me before placing an order with your requirements and available files so I can review the project and recommend the appropriate package.
