Including XOR gates in your functions offers significant benefits by reducing transistor and track counts and increasing testability. As designers, we're used to representing digital functions using ...

Digital gates are fundamentally analog in nature. They use transistors. Sure, these transistors are operated at their conduction extremes (which is why they are called “digital”), but during the logic ...

This is accomplished by sending the 500-ms pulse to an XOR gate (U5A), but to delay one of its pins with the R4-C1 combination. Once the XOR gate generates the two 10-ms pulses, the two NAND gates ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

Figure 1: A four-state molecular switch. As a first step, fluorescein in its neutral state F(0) was obtained in aqueous solution of acetic acid (0.015 M, pH=3.3). Addition of hydrochloric acid (0.013 ...

This study is led by Prof. Hongxin Yang (Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences) and Dr. Dongxing Yu (Ningbo Institute of Materials Technology and ...

DNA-based logic gates that could carry out calculations inside the body have been constructed for the first time. The work brings the prospect of injectable biocomputers programmed to target diseases ...
