A FPP-oriented tone mapping technique for high dynamic range imagers using temporal and final exposure measurements
(Institute of Electrical and Electronics Engineers, 2010)
This paper presents a Dynamic Range improvement technique which is specially well-suited to be implemented in Focal Plane Processors due to its very limited computing requirements since only local memories and a comparator ...

Compensation of PVT Variations in ToF Imagers with In-Pixel TDC
(MDPI, 2017)
The design of a direct time-of-flight complementary metal-oxide-semiconductor (CMOS) image sensor (dToF-CIS) based on a single-photon avalanche-diode (SPAD) array with an in-pixel time-to-digital converter (TDC) must ...

A Wide Linear Dynamic Range Image Sensor Based on Asynchronous Self-Reset and Tagging of Saturation Events
(Institute of Electrical and Electronics Engineers, 2017)
We report a high dynamic range (HDR) image sensor with a linear response that overcomes some of the limitations of sensors with pixels with self-reset operation. It operates similar to an active pixel sensor, but its pixels ...

Transformer based front-end for a low power 2.4 GHz transceiver
(Institute of Electrical and Electronics Engineers, 2010)
A low power transceiver architecture for the 2.4 GHz ISM band using a 1.0 V supply is presented. It employs a transformer to convert the 100 Ω antenna impedance to almost 1 kΩ and so facilitates a low power transmitter and ...

Integer-based digital processor for the estimation of phase synchronization between neural signals
(Institute of Electrical and Electronics Engineers, 2016)
This paper reports a low area, low power, integer-based neural digital processor for the calculation of phase synchronization between two neural signals. The processor calculates the phase-frequency content of a signal by ...

Bottom-up performance analysis of focal-plane mixed-signal hardware for Viola–Jones early vision tasks
(John Wiley & Sons, 2015)
Focal-plane mixed-signal arrays have traditionally been designed according to the general claim that moderate accuracy in processing is affordable. The performance of their circuitry has been analyzed in these terms without ...
