An arithmetic circuit is a set of gates that perform arithmetic operations like addition, subtraction, multiplication, division, and parity calculation. The gates are connected to carry out an arithmetic action, and the outputs of the gate circuit are the digits of the result. 

Arithmetic circuits are combinational circuits that consist of full adders and multiplexers. The select lines of the multiplexer determine which type of operation the arithmetic circuit will perform. 

Here are some types of arithmetic circuits:
Half adder: An arithmetic circuit that needs two binary inputs and two binary outputs to perform the addition of two single bits. Half adders can be realized using universal gates like the NAND and NOR gates.
BCD adder: A circuit that performs arithmetic addition directly in the decimal number system. A BCD adder requires a minimum of nine inputs and five outputs.
Full adder: An arithmetic circuit block that can be used to add three bits to produce a SUM and a CARRY output. Full adders are necessary when it comes to adding binary numbers with a large number of bits.
