MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...

Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

In this column, we take a closer look as to how timing and delays affect our logic circuits. As part of this, we start to consider the timing diagrams presented in data sheets. As I was writing my ...

Non-volatile bistable memory circuits pave the way for highly energy-efficient CMOS logic systems. Non-volatile bistable memory circuits being developed by Satoshi Sugahara and his team at Tokyo Tech ...

Well, summer has been and gone; and for most of us it was a time to relax and reflect on our working practices. What can we do to achieve better results? And what can we do to break out of the routine ...

Select between the Combination or Sequential circuit for analysis (Figure 16). Figure 16: Screen to select Combinational or Sequential Circuit Select the number of inputs (max of 3) and number of ...
