In this article a low power and low latency 4-2 compressor has been presented. By using modified truth table and Pass Transistor Logic (PTL) a novel structure has been proposed which outperforms previous designs from the frequency of operation view point. The proposed design method has reduced the total transistor count considerably which will lead to reduced power consumption and smaller activ...

CMOS image sensors are a second-generation solid­ state imaging technology. CMOS active pixel sensors have performance competitive with CCD technology, and offer advantages in on-chip functionality, system power reduction, cost and miniaturization. CMOS VLSI circuits for imaging and readout, and on-chip integration of ADC and smart functions will be addressed.

CMOS active pixel sensor (APS) technology has been developed as a potential replacement for charge-coupled devices (CCDs) for solid-state imaging. The CMOS APS has several advantages over CCDs for camera systems including much lower camera power, smaller camera size, lower camera cost, and on-chip functionality. This paper describes the CMOS APS technology.

In this paper a new 8-bit 50-Msample/s CMOS digital-to-analog converter (DAC) is presented. The circuit employs 9 operational transconductance amplifiers (OTAs) and CMOS transistors as switching circuit. The proposed DAC is simulated using SPICE simulation program with 3μm CMOS technology. Simulation results shows verify good performance of the circuit.

Silicon-based complementary metal oxide semiconductors have revolutionized the field of imaging, especially infrared imaging. Infrared focal plane array imagers are widely applied to night vision, haze food selection, semiconductor detection, and atmospheric pollutant detection. Over past several decades, CMOS integrated circuits modified by traditional bulk materials as sensitivity sensors for...
