    • A driver circuit includes a first transistor coupled between an input supply node and an output node. The first transistor operates in one of a conductive state to couple the output node with the input supply node and non-conductive state according to cooperative operation of a second transistor and a third transistor. The second transistor is coupled to provide a control input to drive the first transistor to the conductive state thereof in response a first input signal provided at a control input of the second transistor. The third transistor is coupled to provide an output at the output node in response to a second input signal provided at a control input of the third transistor, the first and second input signals being out of phase with each other. Circuitry is coupled between the input supply node and the control input of the first transistor to provide reduced impedance at the control input of the first transistor according to operation of the second transistor.

    • A system and method are provided for determining channel mobility. The system includes a threshold voltage (VT) extractor that extracts the VT associated with a metal oxide semiconductor (MOS) transistor and provides an output signal functionally related to the extracted VT. An oscillator generates an oscillating waveform according to the output signal and a calculator computes an estimate of a channel mobility parameter based on the oscillating waveform. A plurality of the VT extractor and oscillators can be distributed across the wafer to provide an indication of channel mobility for different regions of the wafer.
