LOGIC ELEMENT EMPLOYING NORMALLY ON FIELD-EFFECT TRANSISTORS Russian patent published in 1994 - IPC

FIELD: microelectronics. SUBSTANCE: logic element uses an input inverter consisting of transistors 1 and 2, output source follower consisting of transistor 6, level shift diodes 7 and load transistor 8. Owing to connection between the logic element input and date of load transistor 8 of an additional source follower consisting of transistor 10, diode 11 and transistor 12, and introduction of diode 9, the current of load transistor 8 of the output source follower increases at the positive front of the input signal and decreases at the negative front of the input signal. This results in an increase of current given off to the load and decrease of the time of recharge of the load capacitor. EFFECT: enhanced speed of response of logic element employing normally on field-effect transistors. 3 dwg
