An equivalent MOSFET cell using adaptively biased source-coupled pair
The square-law characteristics of MOSFET in the saturation region have a parameter of threshold voltage V-T. However, it introduces some complexities to the circuit design since it depends on kinds of MOS technology and cannot be controlled easily. In this paper, we show an equivalent MOSFET cell which has V-T-programming capability and some application instances based on it. The simulation is carried out using CMOS 0.8 mum n-well technology and the results have shown the feasibility of the proposed structure.
