Digital logic circuits can be fabricated using either depletion-mode devices alone or both enhancement- and depletion-mode devices. A process for depletion-mode devices only is simpler and has a high yield Design Procedure of Combinational Logic Circuits. A combinational circuit can be designed using the following steps. Identification and determination of number of available input variables and required output variables. Representing symbols (alphabets) for each and every input and output variables * Explanation: A 2^n:1 MUX can implement all logic functions of (n+1) variables without any additional circuitry*. Thus 8:1 MUX can implement all logic functions of (3+1) variables, for 4 variables there are 16 possible combinations. So to use 8:1 MUX use 3 inputs as select lines of MUX and the 4th input as input of MUX

A digital electronic circuit that is made to perform certain logical operations is defined as Logic Gate. It can be designed using any 'Non-Linear Device'. The sole condition is that it must consist of two different regions for operation. The most commonly known devices with non-linear characteristics are Diode and the Bipolar Junction Transistors (BJT). The logic levels of voltages are assigned to the circuits to carry out the operation It is the combinational logic derived by using two inputs and two outputs. The circuit design allowed us to add two one-bit binary numbers. So, the main purpose of using half adder is for addition. With the inputs as A and B, the circuit can be designed as follow When you try yourself solving the min-term SOP of for 3 variables, Users can use this online Karnaugh's map solver for 4 variables to verify the results of manual calculations. step 1 Addressing the cells of KMap table When using KMAP solver, generally users should be careful while placing the min-terms These circuits are designed by using logical gates like AND, OR, NOT, NANAD, NOR, XOR gates which perform logical operations. This representation helps the circuit to switch from one state to another for providing precise output You are required to design a 4-bit even up-counter using D flip flop by converting combinational circuit to sequential circuit. The counter will only consider even inputs and the sequence of inputs will be 0-2-4-6-8-10-0. You are required to perform following tasks: 1. Draw the State diagram. 2. Generate State & Transition Table. 3

Logic circuits are constructed from components that can switch between these the high and low voltages. The basic switching device in today's computer logic circuits is the metal-oxide-semiconductor ﬁeld-eﬀect transistor (MOSFET). Figure 4.25 shows a NOT gate implemented with a single MOSFET Design of Sequential Circuits Using ROMs - Code Converter : A sequential circuit can easily be designed using a ROM (read-only memory) and flip-flops.

Logic circuits have inputs, as well as having outputs which can be dependent on the inputs. In logic circuit diagrams, connection from one circuit's output to another circuit's input is displayed as an arrowhead at the input end. When it comes to performance, logic circuits are similar to programming language functions XOR gate is a digital logic gate that gives a true output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true. If both inputs are false or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is must have one or the other but not both. In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information - a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems.

Although Boolean algebraic laws and DeMorgan's theorems can be used to achieve the objective, the process becomes tedious and error-prone as the number of variables involved increases.
