Abstract :
A new test chip is developed for further studying the test circuit, with which the MOSFET threshold-voltage (VTH) mismatch can easily be evaluated and which is proposed in the previous ICMTS. The data obtained from the test circuits having different design channel width, design channel length, MOSFET number and channel conductivity show reasonable dependency of the VTH-mismatch on those parameters.
