  • Abstract
    An input-free NMOS VT (threshold voltage) extractor circuit in an n-well CMOS process is presented. The non-idealities due to NMOS body effects on the extracted VT are automatically compensated in the circuit. PMOS difference amplifiers are developed to compute the difference of node voltages such that the VT of the NMOS device can be extracted as a voltage, referenced to ground or VDD. The proposed NMOS V2 extractor circuit was fabricated in a 0.25 μm CMOS process, and the extracted VT, which had an absolute value of 0.441V, had an accuracy of 95.7%.
