What is intermodulation, and is it good or bad? Part 2
A mixer can upconvert and downconvert a modulated signal with no loss of baseband information. Part 1 of this series described intermodulation resulting from the combining of two or more sinusoidal signals through a nonlinear device such as the mixer in Figure 1. The mixer’s output is the product of its two inputs, and its […]
How are zinc oxide (sunscreen) WBG nanomaterials used in sensors?
Zinc oxide (ZnO) is a common ingredient in sunscreen lotions. Less well-known is the fact that it’s also a wide band gap (WBG) semiconductor (3.4 eV). As a nanomaterial, ZnO is being used to develop a wide variety of sensor technologies. Sensor applications for ZnO include health monitoring, chemical sensing, biomedical, and environmental sensors. Some […]
