A current amplifier can be realized using transistors.The schematic of a current amplifier circuit using transistors is shown in the figure below. Two transistors are used in this circuit. β1 and β2 are the current gains of transistors Q1 and Q2 respectively. CMOS Fabrication The fabrication of CMOS transistors can be done on the wafer of silicon. The diameter of the wafer ranges from 20mm to 300mm. In this, the Lithography process is the same as the printing press. On every step, different materials can be deposited, etched otherwise patterned. In this article, you'll learn the basics of the CMOS image sensor, including its core components, its block diagram, its strengths and weaknesses, and its applications. An image sensor is one of the main building blocks in a digital imaging system and strongly influences the overall system performance. The two main types of image sensors are A CMOS op-amp (number ICL 7611) controls the input current through a P-channel Hexfet power transistor (No. IRF 9520), then to keep up a constant voltage across the R1. As they are connected in a serial form, so use the together current by I = VREF / R1, while the Vref to be defined by the IC2 is 1.25V. The advantage of this outline are: 1. Power or supply current in a CMOS switch current DAC can be divided into three categories. The first comes from the digital logic and clock section and often directly scales with the sample frequency and the data pattern. CMOS has the advantage that the design will benefit from advances in process and supply voltage scaling. Given a current source as the input, the input section of the current mirror looks like a virtual short circuit and reflects (swaps the direction of flow) this current to produce a current sink (the current exiting the mirror); as a result, we obtain a current sink (figure 11.1a).

The amplifier's maximum output voltage will be 16 volts RMS, which allows an input sensitivity of roughly around 777mV RMS for achieving a full output. The input impedance could be more than 20k. C3 and C8 are employed as the input and output coupling capacitors respectively. C1 enables decoupling for the supply DC. Post Amplifier for Op Amps A standard operational amplifier used with a CMOS inverter for a PostAmplifier has several advantages. The operational amplifier essentially sees no load condition since the input impedance to the inverter is very high. Secondly, the CMOS inverters will swing to within millivolts of either supply.
