WebNov 22, 2024 · Abstract: Small-signal analysis of a slow-light VCSEL amplifier is introduced using a traveling-wave rate equations model. Theoretical calculations show that the small-signal optical modulation bandwidth of the slow-light mode has strong dependences on the slowdown factor and length of the amplifier; it can be boosted to more than 50 GHz.
WebApr 8, 2024 · The reason why small-signal analysis is also used is because we, normally, use those circuits within a feedback a loop. Therefore, they aren't really amplifying the full-swing of your input voltage signal (in case of a voltage-voltage or voltage-current amplifier), but only the error signal. WebJul 29, 2024 · The key to implementing small signal analysis is to first select a DC biasvalue and analyze the behavior of the circuit. The goal is to determine the transresistance (the inverse of the transconductance) for your nonlinear circuit …
