16-bit, 15 MSPS wide-bandwidth precision acquisition system
When the signal is small and the bandwidth is wide, the front-end decides what is measurable. This system resolves signals down to 20 µV at 16-bit resolution and 15 MSPS, combining a low-noise analog front-end with disciplined mixed-signal layout. Delivered end to end, from analog to firmware, by one team.

Scope
What was delivered
- Low-noise analog front-end: the signal conditioning that makes 20 µV signals measurable
- Noise-aware layout: grounding, partitioning, guarding, shielding, and decoupling to protect the noise floor and ENOB
- ADC driver design for settling time and low noise, using SPICE simulation with optimization loops
- Anti-aliasing filter design as part of the precision signal path
- Characterization in an in-house lab: noise floor, sample-rate accuracy, and linearity measured before delivery
FAQ
Common questions
How is the noise performance verified?
Every system is brought up and characterized in the in-house lab before delivery: noise floor, sample-rate accuracy, and linearity are measured, not assumed.
How do you optimize the ADC driver?
ADC drivers are designed for settling time and low noise using detailed SPICE simulation with optimization loops that sweep component values and topologies. The driver is often the dominant noise source in a DAQ system, so it is optimized until the noise budget closes.
Was this system designed entirely in-house?
Yes. The analog front-end, layout, and firmware were delivered by one team as a single end-to-end engagement. Nothing was subcontracted.
How is a project like this priced?
Defined systems like this one are typically delivered for fixed-price milestones agreed after a short scoping call. Open-ended R&D work runs hourly with regular updates.
