Help Needed on 12 Transistor CMOS SRAM Cell Schematic

AI Thread Summary
The discussion centers on seeking assistance with a schematic for a 12 transistor CMOS SRAM cell. The user understands the implementation of inverters and transmission gates but is confused about inverting the buffer input and integrating the components. A response clarifies that the input inversion may simply be a different representation of an inverter and does not impact functionality. The user expresses relief at this clarification, indicating a better understanding of the schematic. Overall, the conversation highlights common challenges in designing SRAM cells and the importance of clear schematic representation.

I am looking for help on a schematic for a 12 transistor CMOS SRAM cell shown below. I understand how to implement the inverter and transmission gates and how a tri state inverter works, but I am confused when it comes to inverting the input of the buffer and how to tie it all together. Thanks in advance.

In terms of "inverting the input of the buffer", it may just be an inverter drawn that way. I'm not familiar with many 12T SRAM circuits, but I believe that an inverter is just an inverter, and showing the inversion circle at the input of the symbol instead of at the output doesn't affect anything (I could be wrong -- I can check at work on Monday).
 
That makes sense, I'm not sure why I got so bogged down in the difference in the symbol. Thanks.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
