MOSFET ( ENHANCEMENT/ DEPLETION) LOAD INVERTERS
MOSFET (ENHANCEMENT/DEPLETION) LOAD INVERTERS MOSFET s with enhancement type driver and resistance as load are not well suited for VLSI circuit fabrication and in other applications as resistance is a passive elements and it is very difficult is fabricate a resistor.Also voltage transfer curves do not show sharper transition and better noise margins. So n MOS transistor as active loads poise a better condidature for inverter circuit. Also n MOS load occupies less chip area as compared to the linear resistor. The n MOS load inverter is again categorised in two parts..The enhancement type n MOS load and depletion type n MOS load.The enhancement load inverter can again operate in two modes the saturation mode and the linear mode. The inverter circuit with saturated enhancement type nMOS load and linear enhancement type load. The gate and drain of the load transistor are connected t...
