DCO designs using delay cells based on novel three transistors XOR and NAND gate have been reported in this paper. Two different design techniques for delay cell have been presented. Output frequencies have been controlled digitally with control world of different lengths. Three bit controlled DCO ...
We can use HDLs such as Verilog for many things; it's most important use, however, is to unambiguously describe a particular circuit. This includes describing its inputs, outputs, and behavior. When used in conjunction with a Field Programmable Gate Array (or, FPGA) board, we can create a...
A semi-block diagram of the four-stage carry-lookahead adder is shown in Figure 8. (Note that pins that carry the same label in different subcircuits are assumed to be connected.) Since each propagated carry Pi+j is the output of an XOR gate, the overall propagation delay of the carry ...
My guess is that IC designers don’t often use PTL for AND gates. The PTL XOR Gate, Version 1 The XOR function is an example of an application in which PTL really does offer significant benefits. Creating a two-input XOR truth table using typical CMOS logic is a bit awkward—twelve ...

{2n,2n−1,2n+1}, even with slightly improved performance, could seem hardly justifiable. Nevertheless, of significantly more interest is the possibility of using it not as a stand-alone circuit but rather as the main building block in various reverse converters for larger multi-moduli RNSs ...

Realize the following function using AND and OR gates. Assume that there are no restrictions on the number of gates that can be cascaded, and minimize the number of gate inputs: ABCE + ABEF + ACD' + A Design and implement a block that acts like following table. ||F1||F0|...

The minimal sum corresponds to a gate circuit in which two-rail circuit inputs are connected to and gates and the outputs of the and gates form the inputs to an or gate whose output is the circuit output. Such a circuit is called a two-stage circuit, since there are two gates ...
