Diode connected MOSFET

  1. Mar 29, 2012 #1

    Can you please let me know how does the attached circuit work?
    Vh and Vl are inputs ; Vbn and Vbp are outputs.

    Thanks in advance.

    Drains of all four MOSFETs are attached to Gates. Thus for all of them Vds=Vgs (> Vgs - Vth). So all of them are in either saturation or cutoff.
    However, if Vh and Vl are inputs VBN and VBP will give same output for sure.
