SUMMARY

The discussion focuses on determining the transfer function of a diode circuit with resistors R1=1k, R2=4k, and R3=7k, specifically analyzing the output voltage (Vo) in relation to the input voltage (Vg). The secondary inquiry involves sketching the transfer function when Vg is defined as a sinusoidal function, Vg = 10sin(0.1t). Participants emphasize the importance of calculating the conduction threshold of the diode to establish the relationship between Vo and Vg accurately.

PREREQUISITES
  • Understanding of diode characteristics and conduction thresholds
  • Familiarity with transfer functions in electrical circuits
  • Basic knowledge of sinusoidal functions and their graphical representation
  • Proficiency in circuit analysis techniques
NEXT STEPS
  • Study the derivation of transfer functions for nonlinear components like diodes
  • Learn about the graphical representation of sinusoidal signals in circuit analysis
  • Explore simulation tools such as LTspice for visualizing diode circuit behavior
  • Investigate the impact of resistor values on the transfer function in diode circuits
USEFUL FOR

Electrical engineers, circuit designers, and students studying electronics who are looking to deepen their understanding of diode circuits and transfer function analysis.

Hello all, long time reader, first time poster. Just in need of some help on finding the transfer function of the following diode circuit, and sketching the graph of this transfer function.


R1=1k, R2 = 4k and R3 = 7k, we want Vo vs Vg.

The follow on question also invloves finding and sketching the transfer function assuming that Vg is a sinusoidal function, Vg = 10sin(0.1t)

Thanks for any help

Welcome to the PF.

Talk it out. At what positive value of Vo will you start to get some conduction through a diode? What value of source voltage does that correspond to? You need to do the work on this problem...
