Autonomous/self-powering image detecting systems and their manufacturing technologies are disclosed. An antenna is used to communicate signals. A first energy harvester is used to harvest energy from blackbody radiation, RF signals, movement/vibration, or combination thereof. A power management system is used which controls the energy flow to and from the energy-storage. An image sensor to take the image, a lens, and a transmitter to transmit the images to an outside device are also used in this invention. According to this preferred embodiment, an energy harvester harnessing energy from blackbody radiation from and within the body, is used to extract enough energy to increase the operation time and also to make precision of the image detecting system.

An interconnection system is provided with reduced capacitance between a signal via and the surrounding dielectric material. By using a non-homogenous dielectric, the effective dielectric constant of the system is reduced. The signal vias are surrounded with some combination of open trenches and/or grounded vias to decrease the effective dielectric constant of the surrounding system, providing shielding from the interference of nearby signal lines and vias. The fabrication techniques provided are advantageous because they can be preformed using today's standard IC fabrication techniques.

A circuit for recovering data from an incoming data stream according to one embodiment includes a capacitor and a substantially constant current source for charging the capacitor. A subcircuit generates a signal causing the capacitor to discharge upon detecting a first type of transition in the incoming data stream, the capacitor re-charging upon being at least partially discharged. A comparator compares a voltage on a node coupled to the capacitor to a reference voltage, the comparator outputting a first signal if the voltage on the node is higher than the reference voltage and outputting a second signal if the voltage on the node is lower than the reference voltage, the first signal being associated with a first logic value, the second signal being associated with a second logic value.

This invention relates to imaging device and its related transferring technologies to independent substrate able to attain significant broadband capability covering the wavelengths from ultra-violet (UV) to long-Infrared. More particularly, this invention is related to the broadband image sensor (along with its manufacturing technologies), which can detect the light wavelengths ranges from as low as UV to the wavelengths as high as 20 &#x3bc;m covering the most of the wavelengths using of the single monolithic image sensor on the single wafer. This invention is also related to the integrated circuit and the bonding technologies of the image sensor to standard integrated circuit for multicolor imaging, sensing, and advanced communication. Our innovative approach utilizes surface structure having more than micro-nano-scaled 3-dimensional (3-D) blocks which can provide broad spectral response. Utilizing multiple micro-nano scaled blocks help to increase the absorption spectra more than the material used as the absorption layer. In addition, utilizing the multiple nano-scaled 3-D blocks help to increase the absorption over the wavelength due to the multiple reflections and diffractions inside the 3-D structures. The absorption layers will be designed to achieve the required quantum efficiency and also required speed.
