Passive Crystals vs Active Oscillators in DSP Circuit Design

1、Passive Crystals——Passive crystals require an oscillator within the DSP chip, with recommended connection methods provided in the datasheet. Passive crystals do not have voltage issues; the signal level is variable, meaning it is determined by the oscillation circuit. The same crystal can be used for various voltage requirements, making it suitable for DSPs with different … Read more

Low-Temperature Hydrogen Sensor Enhanced Performance

Hello everyone, today I would like to share a paper published in 2020 in ACS Sensors, titled “Low-Temperature Hydrogen Sensor: Enhanced Performance Enabled through Photoactive Pd-Decorated TiO2 Colloidal Crystals”. This research indicates that using a sensitive layer based on Pd modified TiO2 long-range ordered crystals in a photo-assisted amperometric gas sensor can achieve excellent H2 … Read more
