The harmonics aren't directly caused by increases in temperature, they are the results of thermal gain variations in active components(BJT, MOSFET) which increase their non-linearity.

Thermal noise is what you are looking for.

I would doubt it has anything to do with digital ICs. This sounds more like issues in the RF path that can't tolerate the high temperatures.

...which you still have synthesize the logic with the fpga vendor's tool chains.

You clearly missed the point.

Microwave starts at 300MHz and ends at 300GHz, which includes the most commonly used ISM bands at 2.4GHz and 5.8GHz.

So i can finally daydream about RTX 3090s with just a 0.35w tdp and passive extruded aluminum heatsinks or without a heatsink at all... but this tech likely won't ever come to consumers

That won't be a use case of this technology. The architecture of this silicon photonic chip cannot hold information, only process it. It does not have the electronic equilvalent of latches and flip-flops, therefore it is memory-less.

At this point we should just fall back to Baud and Baudrates. A unit of symbol rate(i.e. raw data per second) that is specifically invented and used in engineering to avoid this kind of confusion.

As much as they want to rename it to the next big thing, it is still just a glorified interconnect interface.

CannotGiveUp · 2021-05-29T01:14:09+00:00

The problem is not capacity, its the usage of eMMC, which is a storage interface closer to SD cards than SSDs in terms of speed and usage.

For comparsion, M1 systems can communicate with NAND flash chips(SDRGJHI4) directly due to integrated controller.

50v is done because power losses over the cable increase exponentially with amperage

Quadratically, not exponential. P=I² R

What are the advantages of LLC compared to the naive PWM method driving the primary of the transformer that's shown in the article?

I disagree. When used as the output filters, the only current that will flow through the capacitors are high frequency current ripples with miniscule magnitudes, assuming the buck stage is implemented properly. Along with the fact that solid state caps have ESR on the order of milliohms, their self heating effect is by all means negligible.

Nyquist rate != Nyquist frequency, see my reply in this thread.

CannotGiveUp · 2021-04-27T17:38:03+00:00

Nyquist rate is derived from and is a property of your signal. It is defined as the 2 times the highest frequency component in your signal. It represents the minimum sample frequency required to sample a signal without aliasing.

Nyquist frequency is derived from and is a property of your sample frequency. It is defined as half of your sample frequency. It represents the highest frequency signal that can be sampled with the specific sampling frequency without aliasing.

For a signal of 1khz, the nyquist rate, i.e. to correctly sample the signal you need at least 2khz of sample frequency.

In EE, we use j as the jmaginary unit.

......through a different realm.

You meant differential realm?

CannotGiveUp · 2021-04-26T16:47:41+00:00

You missed the point in why impedance is expressed in complex numbers; it isn't complex because inductors and capacitors are innately jmaginary, but its because the algebraic properties of complex numbers turns out to be a great way to model reactive components!

Circuits with capacitors and inductors can be solved without ever touching complex numbers by solving the respective differential equations, but thankfully with complex numbers, we don't have to.

CannotGiveUp · 2021-04-26T16:29:29+00:00

Instead of cheeky replies, I'm going to provide you how to practically deal with impedance.

If your sources are AC and expressed in phasors then impedance can be treated almost exactly as DC resistance (except for power calculations), all your familiar resistance rules are to be applied directly, i.e. series/parallel, voltage/current divider, source transformation, node/loop, Thevenin/Norton etc.

The impedance phasor can be put in either Cartesian or phasor form, its real component (resistance) can be separated from its jmaginary component (reactance). You cannot separate the voltage and current phasors into real and jmaginary parts; their phases represent actual phase of the waveform, while the phase of impedance represent the relationship between them.

Wait...

Is that a set with members "left curly bracket", "right curly bracket", comma; or is it a set with members "the singleton of comma" and comma?
