Latest Patents

Hallgren holds a patent for an "Electronic Sampler Switch." This invention features a low distortion differential sampler circuit implemented in Gallium Arsenide (GaAs). The sampler circuit operates as an on/off switching circuit rather than a traditional sample and hold circuit. By eliminating the holding capacitor, Hallgren's design achieves shorter switching times and reduced error rates. The differential, balanced architecture of the sampler compensates for clock signal feed-through, ensuring high fidelity in signal processing. Additionally, the circuit includes a three-stage, AC coupled GaAs pre-amplifier that provides a complementary clock signal to drive the sampler and sets the appropriate DC levels.
