A sensor includes a photodiode disposed in a semiconductor material to receive light and convert the light into charge, and a first floating diffusion coupled to the photodiode to receive the charge. A second floating diffusion is coupled to the photodiode to receive the charge, and a first transfer transistor is coupled to transfer the charge from the photodiode into the first floating diffusion. A second transfer transistor is coupled to transfer the charge from the photodiode into the second floating diffusion, and an inductor is coupled between a first gate terminal of the first transfer transistor and a second gate terminal of the second transfer transistor. The inductor, the first gate terminal, and the second gate terminal form a resonant circuit.

An image sensor pixel includes a photosensitive element, a floating diffusion region, a transfer gate, a dielectric charge trapping region, and a first metal contact. The photosensitive element is disposed in a semiconductor layer to receive electromagnetic radiation along a vertical axis. The floating diffusion region is disposed in the semiconductor layer, while the transfer gate is disposed on the semiconductor layer to control a flow of charge produced in the photosensitive element to the floating diffusion region. The dielectric charge trapping device is disposed on the semiconductor layer to receive electromagnetic radiation along the vertical axis and to trap charges in response thereto. The dielectric charge trapping device is further configured to induce charge in the photosensitive element in response to the trapped charges. The first metal contact is coupled to the dielectric charge trapping device to provide a first bias voltage to the dielectric charge trapping device.

A fluidic medical diagnostic device permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The desired measurement can be made by placing the device into a meter which measures a physical property of the sample&#x2014;typically, optical transmittance&#x2014;after it has interacted with a reagent in the measurement area.

Fluidic device for medical diagnostics

A fluidic medical diagnostic device permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A first channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. A second channel, which runs from the first channel to an edge of the device, determines whether the sample volume is sufficient to permit an accurate measurement. The desired measurement can be made by placing the device into a meter, which measures a physical property of the sample, typically optical transmittance, after it has interacted with one or more reagents on the device.
