EN-Genius Network's Dennis Feucht answers your design
queries in his new Circuit Design Clinic!
March, 2010
EN-Genius Network presents a new, interactive
analog design service to readers! Send us your design questions (with
relevant data; schematics in JPEG or GIF, please) for some free
engineering advice from EN-Genius Network's circuit
consultant, Dennis Feucht, on how you might solve a design problem or
improve circuit performance. Submissions may be edited for clarity or
brevity, and submitters and their email addresses will remain anonymous
(unless otherwise indicated). Please send your questions to Dennis here.
A User-Proof Connection to an Internal Supply: a Simple Current-Limited Output Circuit 3: Two-BJT Current Limiter by Dennis L Feucht
Some additional improvement in circuit performance can be achieved over the improved one-BJT current-limited supply by adding one transistor.
