Integrated Modulo Sampling ADC

Unlimited Dynamic Range for Next-Gen Wideband Receivers

Solving signal saturation in Software Defined Radios (SDR) and Passive Radar through folding architectures.

The Challenge: Signal Clipping

Conventional ADCs suffer from a limited Dynamic Range (DR). When an input signal (like a powerful radar pulse) exceeds the ADC's voltage ceiling, the signal "clips," leading to permanent data loss and severe distortion.

In modern environments—filled with multi-standard receivers and wideband interference—maintaining high fidelity without saturation is a critical bottleneck for signal processing.

The Modulo Solution

Instead of letting the signal saturate, our architecture applies a modulo operation in the analog domain.

Target Applications

Passive Radar

Detecting targets using existing commercial signals without clipping.

Software Defined Radio (SDR)

Adapting to massive signal variations across multi-standard bands.

Biomedical Instrumentation

Resolving tiny biological signals in the presence of large DC offsets or noise.
