Why it matters
A well-designed schematic guides the layout, speeds up debugging, and documents your product for years.
I design schematics across the full spectrum of electronic circuits: precision analog front-ends, high-speed digital interfaces, RF sections, power management, and mixed-signal designs. Each one is built with a hierarchical structure that keeps a complex design manageable and easy to review. Where it adds value, I run SPICE simulations on analog sections, signal integrity analysis on high-speed digital, and power distribution network analysis, so the design meets its specification before a single component is placed on a PCB. Whether the work stays in KiCad or Altium, clean schematic capture is where a design is really won or lost: correct parts, clear structure, and the review notes that stop an error propagating into layout.
What you get
Deliverables you and your manufacturer can build from
Component library
Verified component symbols with accurate pin mappings, linked to PCB footprints and supplier data.
Bill of materials
A complete BOM with manufacturer part numbers, alternates, and supplier links.
Simulation results
SPICE simulation reports for critical analog circuits, including frequency response, transient analysis, and noise analysis.
Design calculations
Documented calculations for component values, power dissipation, timing, and other design parameters.
Design review package
Annotated schematics highlighting critical areas, design decisions, and layout constraints.
Native design files
Altium Designer project files for your records and future modifications.
Problems avoided
The circuit failures a professional schematic prevents
Component selection errors
Wrong voltage ratings, inadequate current capacity, or incompatible logic levels.
Missing protection
Lack of ESD protection, reverse polarity protection, or overcurrent limiting.
Power integrity issues
Insufficient decoupling, poor power sequencing, or inadequate bulk capacitance.
Signal integrity problems
Impedance mismatches, crosstalk, or inadequate termination on high-speed signals.
Thermal oversights
Components operating outside safe temperature ranges under worst-case conditions.
Documentation gaps
Schematics that are difficult to read, review, or maintain.
How it works
A clear path from architecture to a verified schematic
1
Architecture definition
I develop a block diagram showing the major functional blocks, interfaces, and signal flow, which establishes the hierarchical structure of the schematic.
2
Component selection
I select components based on performance requirements, availability, cost, and reliability, and verify every part for current production status and lead times.
3
Circuit design
I design each functional block in detail, including component value calculations, simulation where needed, and application of best practices.
4
Schematic capture
I create the formal schematics in Altium Designer with proper hierarchy, clear annotations, and design rule constraints for PCB layout.
5
Review and verification
I run a comprehensive design review including electrical rule check (ERC), simulation verification, and documentation review before proceeding to PCB layout.

Questions
Frequently asked
What tool do you design in?
Altium Designer, with clean hierarchical schematics that are easy to review, maintain and hand off.
Do you only draw schematics or also lay out the board?
I do both. A schematic is most useful when the person drawing it is also thinking about the layout, so the two stay consistent.
Can you verify the circuit before layout?
Yes. I use simulation where it adds value to check critical parts of the circuit before committing to a board.
Will I get clean documentation?
Yes. The deliverables are organised, readable schematics and a bill of materials that your team or a manufacturer can work from.
Do you work in KiCad and Altium for schematic capture?
Yes. Schematic capture is done in KiCad or Altium, whichever your project uses, with correct component selection, a clear and reviewable structure, and a schematic review pass so mistakes are caught before they reach layout and become expensive.
Ready when you are
Ready to design your circuit?
Whether you need a complete schematic design or a review of an existing circuit, professional engineering makes sure your design works the first time.
