Accessing an SRAM Array?

As im learning about Computer Architecture im trying to understand it from the ground up (Transistors in CMOS in particular) I came across the simple 6T schematic for SRAM (2 inverters) Mostly ...

CMOS Inverter Voltage Transfer Function

So let's say I have a perfectly symmetrical Voltage transfer function curve for my CMOS inverter. The curve looks like this: The question is, how would this curve change if the size of the NMOS ...

CMOS vs TTL Logic Gates?

This is probably a simple question but how come CMOS Logic Gates built from Only Transistors is completely different from one that uses TTL Logic (Like BJT's). I know BJT aren't really used anymore ...

CMOS inverter with gate of PMOS transistor always grounded

If there is a CMOS inverter such that the gate of the PMOS transistor is always attached to the ground and the input voltage is only applied to the gate of NMOS, then how would the inverter behave, as ...

Do I need to duplicate the 4th “substrate” connection when building CMOS gates out of discrete transistors?

All CMOS digital integrated circuits I've ever seen connect all the nFET substrates together to GND. In particular, the IC CMOS NAND gate has one nFET that has its substrate connected to GND, but its ...
