Latest Patents

Kosaka's latest patents include a solid state imaging element, an imaging apparatus, and a method for controlling solid state imaging elements. The solid state imaging element features a current source, a pixel circuit, a comparison circuit, a control section, and a counter. The current source generates a constant current, while the pixel circuit produces a pixel signal that exceeds a predetermined lower limit voltage based on the conductance of the current source. The comparison circuit amplifies this pixel signal at a specific amplification rate and compares it with a predetermined reference signal. The control section adjusts the conductance as the amplification rate increases, and the counter tracks count values until the comparison result is inverted.

The imaging device aims to minimize errors in inversion timing when comparing an analog pixel signal with a reference signal. It includes a load current source, a comparator with an input transistor, and capacitors that facilitate the input of the reference signal and maintain a reference potential. This innovative design enhances the reliability of imaging devices and their associated electronic apparatuses.
