Electronic components combinational circuits
Integrated circuit is a kind of the use of special process, to integrate the elements such as transistors, resistors, capacitors, formed on a silicon substrate has a certain function of the device, the English abbreviation for IC, also commonly known as the chip.
Analog integrated circuit is to point to by elements such as capacitor, resistor, transistor integrated together to deal with analog signals of analog integrated circuits. There are a lot of analog integrated circuits, such as the integrated operational amplifier, comparator, logarithmic and exponential amplifier, analog multiplication (except) multiplier, phase-locked loop, power management chip, etc. Analog integrated circuit of main circuit are: amplifier, filter, feedback circuit, reference source circuit, switch capacitor circuit, etc. Analog integrated circuit design is mainly done by experienced designers manual circuit debugging, simulation and get, and the corresponding digital integrated circuit design is mostly through the use of hardware description language in EDA software under the control of automatic synthesis.

Digital integrated circuit is to integrate the components and wires in the same made of semiconductor chip and digital logic circuit or system. Based on digital integrated circuit containing gate or yuan, the number of devices, digital integrated circuit can be divided into small-scale integration (SSI), medium scale integration (MSI) circuit, large scale integration (LSI), very large scale integrated circuit VLSI circuits and elsi ULSI) circuit. Small-scale integrated circuit containing gate within 10, or components for not more than 100; Medium scale integrated circuit containing the gate between 10-100, or the number of components between 100-1000; Large scale integrated circuit consists of a gate in the more than 100, or the number of components between 10-10. Very large scale integrated circuit containing gate in more than 10000, or the number of components in between 10-10. Large scale integrated circuit on the number of components between 10-10. It includes: the basic logic gates, flip-flop, register, decoder, drives, counter, shaping circuit, programmable logic devices, microprocessor, microcontroller, DSP and so on.
