Figure 1 shows a polarization circuit applicable to ISFET (ion-sensitive field-effect-transistor) sensors. ISFETs are solid-state chemical sensors that measure the pH value of a solution in biomedical and environmental applications, for example. ...

As a youngster, I saw some really old radios; the kind that occupied highly-polished wooden cabinets the size of a refrigerator. When those old radios were made, permanent magnets were not all that powerful, at least by today’s standards, and ...

Some years ago, back in 2005 to be specific, the project was a power supply for a low Earth orbiting satellite. Part of our digital circuitry involved some logic gating using Exclusive-OR (Ex-OR) devices of type CD4070BMS . All was well until we ...

What is Air Pollution? Air pollution is the presence of excessive amount of unwanted harmful solid and gases substances in the air. Cause and Effect of Air Pollution Recently, many cities in the world have encountered rapid urbanization and this ...

It is not often you get to write a title like the one above. The main methods of generating electricity have been know for years, decades or even centuries. Over that time they have been refined, redesigned, rebuilt with better materials and more ...

Part 1 The safety shield surrounds the electrostatic shield, protecting the instrument user from hazardous voltages on the DUT, or the measurement leads. The safety shield should be connected to earth ground at the instrument, and it should have a ...

Trust JLCPCB EasyEDA The consolidation of JLCPCB EasyEDA JLCPCB and EasyEDA assembled. The core reason of Co-branding is for better serving the coming future electronic products and the coming future tech-world. JLCPCB is known as a multilayer PCBs ...

Inadequate shielding and bad grounding are often blamed when measurements are inaccurate, especially in high-impedance applications. In fact, shielding and grounding problems are frequently responsible for measurement errors, but many test system ...

Editor’s note: Jim McLucas, author of the Design Idea Circuit measures capacitance or inductance wanted to respond to some discussion about using this Design Idea. Please see the following that may help. This is an analysis of the effect of ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup in Figure 1, you can measure capacitance or ...
