Hi,
No.
An oscillator consists of an amplifier and a frequency dependent feedback.
An XTAL does not oscillate without an amplifier.
The amplifier is built inside, the frequency determining feedback (XTAL) is built outside.
The amplifier alone does not determine the frequency. The frequency is...
External clock .. is external, internal is internal.
It´s not where the inverter/amplifier sits, it depends where the frequency determining part is.
External clock: XTAL = externally connected. XTAL is the device that determines the clock frequency .. accuracy and stability.

Hi,
according the datasheet it shows 360mA at 200MHz and 320mA at 166MHz.
Thus the dynamic consumption is 40mA/36MHz or 235mA at 200MHz.
The static current is 360mA - 235mA = 125mA. at 50% duty cycle it´s about 65mA.
The other 50% is standby current of 30mA. --> 15mA
So total 315mA.
But...
Hi,
thermocouple measurement is a differential measurement of cold junction temperature and thermocouple temperature.
If the cold junction is at room temperature and the thermocouple is at room temperature .. then it measures ... nothing!
So if you want to measure absolute temperature at the...
I guess this will be one of the future tasks of the AI algorithm. The problem is that when a thousand sites say so .. then AI will repeat it, how often? And every time it repeats it it will become even more trustworthy for an AI. I´m not sure how this can be stopped.
It is similar to how...
Hi,
VSS = GND = 0V
It simply means that the POR circuit works down to zero supply voltage.
This may sound suspicious, because no semiconductor can work down to 0V supply voltage. Instead it means the POR output (let´s say it is a low_active signal) is pulled low by an internal resistor. And...
Hi,
For voltage measurement you always need two nodes.
* one is the voltage you want to measure
* the other is the reference node. they often are called: GND, AGND (analog GND), DGND (digital GND), 0V. Since it is the reference point it always is considered to be zero.
You also will see the...
Hi,
Heat is generated on the chip:
In one case the way for heat spreading is:
* chip --> metal sheet --> thin isolation plastics --> external heatsink
Where the chip is directly mounted on the metal heat spreader, and the metal provides a rather large area to transport the heat to the...
Hi,
It´s a POR circuit .. and it does what it´s name says. It RESETs the device on POWER_ON.
* power OFF your device. OFF! Not just "lower the voltage a bit".
* then switch POWER ON
* and it will RESET the device.
As the description says: it gives the registers their default state and it...
Hi,
I guess it already is. I guess some of the ones who ask questions here use AI, as well as some of those who answer questions.
And I´m quite sure in future we will have AI as a direct "forum member".
I can´t see how. People ask questions. Some of them ask questions that have already been...
Hi,
LM311 is a comparator - as you already mentioned.
But you used it like an OPAMP with external gain setup of +1.
--> Don´t use a comparator this way.
An OPAMP is no comparator and a comparator is no OPAMP. Both are designed for completely different operation modes.
Sadly they share the...
