Systems and methods are described for a tetracell image sensor that performs diamond binning to process image data. An image sensor includes a pixel array and a converting circuit, where the pixel array includes pixel sets arranged in a row direction and a column direction, outputs a first signal generated from a first pixel set of the pixel sets, and outputs a second signal generated from a second pixel set of the pixel sets. The converting circuit performs binning based on the first signal and the second signal to generate a first binning signal. Each of the first pixel set and the second pixel set includes pixel sensors adjacent to each other, and the first pixel set and the second pixel set are located at different rows and different columns.

The present technique discloses a buck-boost converter. According to a detailed example of the present invention, a number of switching elements of a buck-boost converter is reduced compared with a conventional buck-boost converter, and thereby a buck mode and a boost mode are performed with reduced overall conduction loss and switching loss. In addition, a buck-boost converter that is capable of stepping up and down an input voltage over a wide range using a single control device, that has a simple structure, that has inexpensive manufacturing costs, and that has a high circuit integration density can be realized by configuring the buck-boost converter to connect a two-phase interleaving boost converter unit to a single-phase buck converter unit.

In one embodiment, the modulator in an analog-to-digital converter includes a first reset switch and second reset switch, each controlled by a reset signal. The first reset switch is connected in a first reset feedback path between an input and an output of an integrator stage, and the second reset switch connected in a second reset feedback path between the input and the output of the integrator stage.
