AI Thread Summary
Schottky diodes exhibit better frequency response than PN diodes primarily due to their lower junction capacitance and faster switching speeds. The metal-semiconductor junction in Schottky diodes allows for rapid charge carrier movement, reducing the time it takes to turn on and off compared to PN diodes. Additionally, the absence of minority carrier storage in Schottky diodes minimizes delay, enhancing their performance in high-frequency applications. Understanding these properties is crucial for applications requiring efficient signal processing. Overall, Schottky diodes are preferred in high-frequency circuits due to their superior response characteristics.

I studied semiconductor basic long time ago... So I've reviewed these days.
For a while, i got a question about Schottky diode's frequency response.
That is Schottky diode has more awesome frequency response than pn diode.
Why does Schottky diode has good frequency response?
Somebody help me... I need your help...

Welcome to the PF.

What has your reading told you so far about the differences between standard and Schottky diodes? What kind of property would affect the frequency response of a diode?
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
