Abstract
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 V 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.
