The imager system of the invention, provided in a semiconductor substrate, includes a plurality of photosensitive, charge integrating pixels that are arranged in rows and columns of a pixel array for capturing illumination of a scene to be imaged. Each pixel includes a photogenerated charge accumulation region of the semiconductor substrate and a sense node at which an electrical signal, indicative of pixel charge accumulation, can be measured without discharging the accumulation region. Pixel access control circuitry is connected to pixel array rows and columns to deliver pixel access signals generated by the access control circuitry for independently accessing a selected pixel in the array. An input interface circuit is connected to accept a dynamic range specification input for the array pixels. Integration control circuitry is connected to access a selected pixel of the array to read the sense node electrical signal of the selected pixel, and configured to generate pixel-specific integration control signals delivered to the selected pixel, independent of other pixels, based on dynamic range specification input provided by the input interface circuit. An output interface circuit is connected to the pixel array to produce output image data based on sense node electrical signals from the pixel array.

Multi-mode crystal oscillator system selectively configurable to minimize power consumption or noise generation
ActiveUS6959217B2Limited amountNoise minimizationElectrotherapyPulse automatic controlNoise generationSignal-to-noise ratio (imaging)
The present invention is directed to a multi-mode crystal oscillator system selectively configurable to minimize power consumption or noise generation. Such a system is particularly applicable to the communication system of an implantable device, e.g., the microstimulator / sensor device described in U.S. Pat. Nos. 6,164,284 and 6,185,452. In such devices, their small size limits the size of the battery contained within and thus makes it essential to minimize power consumption. Additionally, the small size and battery capacity result in a limited transmission power. Furthermore, the small size limits the antenna efficiency which makes it desirable to limit any noise generation to maximize the signal-to-noise level of the resulting receive signal. Accordingly, embodiments of the present invention alternatively supply power to the oscillator in either a first mode that minimizes power consumption or a second mode that minimizes noise generation.

One embodiment of the present invention sets forth a mechanism for transmitting and receiving ground-referenced single-ended signals. A transmitter combines a direct current (DC) to DC converter including a flying capacitor with a 2:1 clocked multiplexer to drive a single-ended signaling line. The transmitter drives a pair of voltages that are symmetric about the ground power supply level. Signaling currents are returned to the ground plane to minimize the generation of noise that is a source of crosstalk between different signaling lines. Noise introduced through the power supply is correlated with the switching rate of the data and may be reduced using an equalizer circuit.
