摘要： A video bus for an array of pixel amplifiers is designed for a minimum quiescent current draw. The pixel amplifiers (or column amplifiers) are designed with high impedance pull-ups and low impedance pull-downs to conserve over-all power dissipation. The video bus is provided with a high-impedance P-FET to reset the bus to drain voltage VDD for a very short time between the time one pixel (or column) is selected the time the next is selected, so that the video bus only has to be discharged through the low impedance N-FET. The bus does not have to be current-sourced by the P-FET.

摘要： A pixel cell with increased dynamic range is formed by providing a floating diffusion region having a variable capacitance, controlled by at least one gate having source and drain regions commonly connected to the floating diffusion region. The gate has an intrinsic capacitance which, when the gate is activated, is added to the capacitance of the floating diffusion region, providing a low conversion gain readout. When the gate is off, the floating diffusion region capacitance is minimized, providing a high conversion gain readout. The gate may also be selectively switched to mid-level. At mid-level, a mid-level conversion gain, which is between the high and low conversion gains, readout is provided, but the gate still provides some capacitance to prevent the floating diffusion region from saturating.

摘要： An improved analog-to-digital converter wherein a minimal amount of circuitry is provided for conversion of an analog signal to a series of digital bits. A comparator is provided for generating digital values to which the digital bits correspond. A digital-to-analog converter is provided for generating, via successive approximation, a feedback analog signal based on bits previously generated by the comparator. The analog-to-digital converter compares the feedback analog signal to the input analog signal, and based on the comparison generates a digital value that corresponds to a digital bit. In the method of the invention, an analog signal is converted to a digital value using the analog-to-digital converter, and a digital-to-analog converter comprising two capacitors and a reference selector generates, via successive approximation, a feedback analog signal that is applied to a comparator for comparison to the input analog signal being digitized.
