I have extensive experience in hardware design creating hundreds of electronic circuits of all types, from the chip level to circuit boards to full systems of interconnected modules, for products such as:
- Handheld diagnostic tools
- Automotive engine controls
- Bicycle power meter & computer
- Mixed-signal ASIC for Picture-In-Picture (PIP) TV product
- Set-top boxes (browse the Internet through your TV)
- Laptop computers
- PC expansion cards
- Embedded systems
- Printers
- USB adapters
- LCD display controllers
- Logic analyzer
- Data recorders
- Battery chargers
- Factory automation
- Laboratory instruments
- Emission test equipment
- Vehicle data monitoring
- Powerline communications
- Digital communications
- Household “Smart” Appliances
- Power supplies and power conditioners
Here are some of the types of circuits I have incorporated in my designs:
Circuits can be classified as analog (continuously variable signals like audio, video, sensor readings) and digital (on/off logic, usually very high speed). Many circuit boards and systems I design blend the two, requiring extra care to keep the sensitive analog signals clean and free of interference from the digital sections.
