Luckily, there’s a fully featured free and open source circuit simulation software called Qucs (Quite Universal Circuit Simulator), released under the GPL, that offers a decent alternative to ...
That’s the reason for the vast versions of SPICE available now decades after the original was released, not all of which are as open or free as we might like. Qucs is a GPL circuit simulator.
The method of open-circuit time constants (OCTC) is a powerful approximate analysis tool that allows estimation of the high-frequency 3dB bandwidth of circuits containing resistors, capacitors and ...
For example, a 0.1-nH via hole has 22 ohms of reactance at 35 GHz. As an alternative to a DC short to ground, we can use an RF short circuit, a quarter-wavelength transmission line terminated in an ...
“Our solar cell achieved the highest open-circuit voltage for InGaP/InGaAs/Ge of different size in the literature to our knowledge,” the research's lead author, Corentin Jouanneau, told pv magazine.
JA Solar's Bycium+ cell has achieved a significant breakthrough, having reached a new high in cell efficiency and set a new record with an open-circuit voltage of 748.6mV—the highest in the commercial ...
