Here the capacitance of capacitor C1 is multiplied by approximately the transistor's current gain (β). Without Q, R2 would be the load on the capacitor. With Q in place, the loading imposed upon C1 is simply the load current reduced by a factor of (β + 1). Consequently, C1 appears multiplied by a factor of (β + 1) when viewed by the load.
Since ports are only attached to node 1 and node 4, nodes 2 and 3 need to be removed through Kron reduction. The table below shows the reduced Y parameter matrix of the Chebyshev filter example simulation after nodes 2 and 4 are eliminated. The nodes of the reduced table are renumbered to 1 and 2.
It is the time required to charge the capacitor, through the resistor, from an initial charge voltage of zero to approximately 63.2% of the value of an applied DC voltage, or to discharge the capacitor through the same resistor to approximately 36.8% of its initial charge voltage.
At this stage both devices and circuits were specific to the targeted simulator or specific versions thereof. [2] In particular, neither was Qucsator based on SPICE, nor did a SPICE based simulator replace Qucsator at any given time. In the meantime, Qucs has been forked to accommodate specific needs, most notably Caneda and Qucs-S.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Figure 1: Essential meshes of the planar circuit labeled 1, 2, and 3. R 1, R 2, R 3, 1/sC, and sL represent the impedance of the resistors, capacitor, and inductor values in the s-domain. V s and I s are the values of the voltage source and current source, respectively. Mesh analysis (or the mesh current method) is a circuit analysis method for ...
This circuit does not have a resistor like the above, but all tuned circuits have some resistance, causing them to function as an RLC circuit. An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that ...
The voltage proof of aluminum oxide, the dielectric layer of aluminum electrolytic capacitors, is approximately 1.4 nm/V. For a 6.3 V capacitor therefore the layer is 8.8 nm. The electric field is 6.3 V/8.8 nm = 716 kV/mm, around 7 times lower than in the double-layer.
