Latest Patents
Henley's most recent patent is titled "Ultra-high-speed digital test system using electro-optic signal sampling." This advanced system is designed for semiconductor integrated circuits and utilizes electro-optic sampling techniques to perform tests at data rates of up to 1.2 Gb/s. The receiver portion of the tester boasts a bandwidth of 4.5 GHz and can execute ECL level functional tests with one sampling pulse per vector. The design includes a test head where the device under test is positioned, along with an electro-optic birefringent crystal sensor located below it to minimize signal path length. The system control unit features a Nd: YAG modelocked laser that generates optical pulses, which are directed to an array of reflective contacts on the sensor. The sensor operates as a Pockels cell, with the electric field in the crystal sensor influenced by voltages on the array of contacts, altering the transmission of polarized light through the crystal. Reflected pulses are then received and converted into electrical signals that indicate the voltages on the array of contacts on the electro-optic sensor.
