    what are the impacts of transistor mismatching?????

    what are the problems that com a cross if there is no matching? Is it causes to chip failure, what are the adverse effects??

    Mismatch not cause chip failure, it may give u wrong results for ur inputs

    Yes.... mismatching means amount of signal reaching at particular point at given time will be different which impact the circuit performance.

    Re: what are the impacts of transistor mismatching?????

    In general transistor mismatch refers to the measurable differences in the electrical proporties such as Ic, β, gm between two identically designed and layout devices. Analog designers think a lot about matching.
    Basic operations of some circuits like ADCs directly depends on matching.
    The CMRR of an op-amp limited by matching since it uses differential amlifier, and offsets greatly degrade the performance of bandgap references.
    Mismatch leads to device-device threshold voltage variations.
