Picoammeter circuit capable of handling wide voltage range

Picoammeter circuit capable of handling wide voltage range

“The evaluation of analog switches, multiplexers, operational amplifiers and other ICs poses a challenge for IC test engineers. A typical test requires applying a test voltage or forced voltage to the input of the device and measuring any resulting leakage current and offset current, which is often performed at the level of 1pA or lower. The low-power measurement circuit in […]

An article to understand the surface acoustic wave (SAW) technology sensor

An article to understand the surface acoustic wave (SAW) technology sensor

“Surface acoustic wave technology is an emerging science and technology developed in the late 1960s. It is a marginal subject combining acoustics and electronics. Since the propagation speed of SAW is 100,000 times slower than that of electromagnetic waves, and it is easy to sample and process on its propagation path, using SAW to simulate various functions of electronics can […]
