Another type – the electrochemical capacitor – makes use of two other storage principles to store electric energy. In contrast to ceramic, film, and electrolytic capacitors, supercapacitors (also known as electrical double-layer capacitors (EDLC) or ultracapacitors) do not have a conventional dielectric. The capacitance value of an electrochemical capacitor is determined by two high

Dynamic random access memory (DRAM) stores data in a capacitor. These capacitors leak charge so the information fades unless the charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory. The advantage of DRAM is its structural simplicity: only one transistor and a...

Adaptive capacitors can be widely used in various pixel structures to achieve high DR imaging. Based on the 55 nm CMOS process platform, the research on an adaptive capacitor to improve the DR is carried out in a 12,288 × 12,288 ultra-large array infrared image sensor chip.
To study the real effect of inversion MOS capacitors for high-dynamic infrared image sensors, the 55 nm 1P4M CIS process platform was used to build a 12,288 × 12,288 pixel array infrared image sensor structure based on an adaptive capacitor. The structure of the adaptive capacitor infrared image sensor is shown in Figure 3.
It achieves excellent performance with low noise in low light. To study the change in capacitance value of the adaptive integrating capacitor under different light intensities, the pixel CDS signals using the adaptive integrating capacitor and a fixed capacitance value capacitor as the integrating capacitor is compared.
Figure 9 shows that the adaptive capacitor pixel has less noise (0.3–1.8 e −) compared with the small capacitor of 6.5 fF, and a larger FWC (1.1 Me −) compared with the large capacitor of 37.5 fF. According to Equation (1) of DR, it can be seen that DR is determined by two factors, QFWC and Qnoise.
To this end, a highly dynamic pixel structure based on adaptive capacitance is proposed, so that the capacitance of the infrared image sensor can automatically change from 6.5 fF to 37.5 fF as the light intensity increases.
The pitch of the adaptive capacitor pixel is only 5.5 µm, which is much smaller than 16 µm of [ 11 ], 22 µm of [ 16 ], and 15 µm of [ 21 ], which is very advantageous.
