Area-Efficient Readout IC with High Panel Noise Rejection for Capacitive Touchscreens

As capacitive sensing provides flexible and reliable touch user interfaces for a varied set of applications, it has gained popularity over other touch sensing techniques. Consequently, capacitive touchscreens when interfaced with large display panels increases the number of channels that a readout IC has to support. As existing area-intensive...

Verification of the non-local avalanche current model in mextram for advanced SiGe HBTs

To realize optimum performance, SiGe HBTs are typically designed with heavily doped implanted collectors. For practical circuits operating at either high collector current density (Jc) or high collector-base voltage (Vcb) avalanche multiplication is an important effects that must be accurately measured and modeled. For example in digital...

A Micro Surgical Instrument for Age Related Macular Degeneration

Age-Related Macular Degeneration (AMD) is a degenerative condition of the macula, which results in a loss of vision. AMD is a common contributor to vision loss in adults over the age of 50. In Western countries, AMD affects nearly 30% of the individuals over the age of 75. In the Rotterdam Eye Hospital an experimental surgical procedure has been...

Data Acquisition System Design for a 160x128 Single-photon Image Sensor with On-pixel 55 ps Time-to-digital Converter

Time-resolved image sensors enabling picosecond resolutions over large formats are needed in many advanced imaging fields, from fluorescence lifetime imaging microscopy (FLIM) to positron emission tomography (PET). Integrated single-photon avalanche diode (SPAD) technology embodies the new frontiers of time-resolved imaging, namely better...
