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 … WebApr 15, 2024 · This paper summarizes the results of investigations of bipolar transistors made in VESTIC (Vertical Slit Transistor-based Integrated Circuits) technology. This technology was proposed by W. Maly as an alternative to classical bulk CMOS technology. However, the basic VESTIC cell can be used not only to make field effect transistors but …
