Calculating BJT Dynamic Parameters with Charge Control Equations

AI Thread Summary
Recommendations for texts on calculating BJT dynamic parameters like fall time, rise time, saturation time, and final rise time using charge control equations are sought. The user notes that "Microelectronic Circuit Design" by Jaeger/Neamen lacks detailed examples. A suggestion is made to review the Gummel-Poon model derivations, which include junction capacitance. Additionally, it's emphasized that understanding these digital parameters requires knowledge of circuit topology and input pulse waveform parameters. Comprehensive resources are essential for accurate calculations in BJT dynamics.

Hi!

Can anyone recommend a text that goes through calculation in fall time, rise time, saturation time and final rise time thoroughly with some examples provided?

I've looked through microelectronic circuit design by Jaeger / Neamen, they briefly mention the concept at best but do not have any examples nor problems that I can work on.

edit: I'm looking for a discussion on how to calculate these numbers by using charge control equations. For example, the delay time can be calculated from relating the average current and the equivalent capacitance in the junction.

Thank you!

If you want just charge control, review Gummel-Poon model derivations that include the junction capacitance.

Be aware this isn't enough to know any of these digital parameters: circuit topology and input pulse waveform parameters are equal contributors.
 

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 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
