Give a big picture of the entire SRAM Layout showing your placements of SRAM Cells, Row Decoders, Column Decoders, Read Circuit, Write Circuit and Buffers
1116Draw the Differential Sense Amplifier and explain its working. Any idea how to size this circuit? (Consider Channel Length Modulation)
1374In the design of a large inverter, why do we prefer to connect small transistors in parallel (thus increasing effective width) rather than lay out one transistor with large width?
1199Draw Vds-Ids curve for a MOSFET. Now, show how this curve changes considering Channel Length Modulation.
1214Given a layout, draw its transistor level circuit. (I was given a 3 input AND gate and a 2 input Multiplexer. You can expect any simple 2 or 3 input gates)
1206Draw the timing diagram for a SRAM Read. What happens if we delay the enabling of Clock signal?
1135Approximately, what were the sizes of your transistors in the SRAM cell? How did you arrive at those sizes?
1152
What types of CMOS memories have you designed? What were their size? Speed?
Draw Vds-Ids curve for a MOSFET. Now, show how this curve changes with increasing transistor width.
Help with VHDL programming. Write a VHDL code for a D-Latch with clear input ?? (Hint: Set up a “Process” with appropriate sensitivity list to get the desired D-Latch with Clr working.) Inputs AND OUTPUTS: entity Lab4b is Port ( Clr, Clk, D : in STD_LOGIC; Q : out STD_LOGIC); end Lab4b;
