FesZ Electronics | Setting the operating point using Active methods @FesZElectronics | Uploaded September 2022 | Updated October 2024, 11 hours ago.
#169 In this video I continue to look at methods to stabilize the bias point of a transistor amplifier, this time by using active methods. I first look at what can be done on the design and component selection part and then look at some active electronic compensation methods.

#127 In this video I try to improve on the original design of the LISN by addressing some of its issues and taking a more detailed look at the inter-channel isolation. Things dont turn out exactly as planned but some valuable insight can be observed nonetheless.

#114 In this video I look at the specifications and parameters behind a line impedance stabilization network, or LISN. I look at what is the purpose of the various components is and then take a closer look at how the values need to be chosen. Finally I build such a device.
