FAQ
What inputs are needed to begin my analog or mixed-signal PCB layout?
You should provide your target sensor datasheets, desired sampling rates, signal levels, power rails, board size constraints, and microcontroller preferences. If you do not have a completed schematic, I can design the analog front-end and schematic from scratch based on your specifications.
How do you prevent noise coupling between digital logic and analog signals?
I enforce strict physical partitioning between analog and digital sections, utilize dedicated ground planes connected at a single star-ground point, route differential signal pairs with matched impedances, and apply guard rings around sensitive high-impedance nodes.
Which sensor types can you design interface circuits for?
I design interfaces for thermocouples, RTDs, strain gauges, photodiodes, MEMS accelerometers, piezoelectric transducers, capacitive sensors, and bio-potential electrodes, tailoring signal conditioning to each sensor's impedance and noise profile.
Do you perform analog circuit simulations before finalizing the PCB layout?
Yes, I use LTspice to simulate active filters, amplifier frequency responses, noise bandwidths, and stability metrics to verify sensor signal conditioning integrity prior to routing the physical board.
Can you integrate microcontrollers like ESP32 or STM32 onto the mixed-signal PCB?
Yes, I regularly integrate microcontrollers, wireless SOCs (ESP32, STM32, Nordic), high-resolution external ADCs/DACs, and communication buses (SPI, I2C, UART) on the same board alongside the analog front-end.
