WebUniversity of Connecticut 60 Diode-Transistor Logic (DTL) n If all inputs are high, the transistor saturates and V OUT goes low. n If any input goes low, the base current is diverted out through the input diode. The transistor cuts off and V OUT goes high. n This is a NAND gate. n The gate works marginally because V D = V BEA = 0.7V. Improved gate with … WebzA BJT is physically just two back to back PN diodes, with three contacts, but the current between the emitter and the collector is a minority carrier current in the base. zEssentially, a forward biased diode is used to create a minority current, most of which then goes all the way across to the depletion region of another, reverse biased diode.
