  • Abstract
    Analog circuit designs are often biased to work in sub-threshold mode with good gate-source voltage matching performances. Depending on the process, hump effect may change the MOS characteristics for negative Bulk-Source Voltage (VBS) and have a slight impact for VBS=0V. To model the hump effect, two narrow parasitic MOS are introduced in parallel with the main device. To accurately simulate matching degradation in sub-threshold mode, these parasitic transistors, in case of hump effect, have to be considered.
