Dec 10, 2014 · Pseudo nMOS based sense amplifier (PNSA) is proposed for high speed single-ended SRAM sensing. The voltage characteristic of pseudo nMOS is utilized to resolve the performance problem of the conventional domino sensing due to full swing bit-line requirement. Increase in dynamic power due to always-on pull-up pMOS in the pseudo nMOS structure is mitigated by introducing a feedback path. As a ...

The second gate electrode forms an input to the inverter, and the second drain electrode is connected to the first drain electrode to thereby ...
This roughly equivalent to use of a depletion load is Nmos technology and is thus called 'Pseudo-NMOS'. The circuit is used in a variety of CMOS logic circuits. In this, PMOS for most of the time will be linear region. So resistance is low and hence RC time constant is low. When the driver is turned on a constant DC current flows in the circuit.NMOS Only Complementary CMOS. EE241 4 UC Berkeley EE241 J. Rabaey, B. Nikoli ... pseudo-NMOS VT <0 Goal: to reduce the number of devices over complementary CMOS. EE241 10Pseudo-nMOS In the old days, nMOS processes had no pMOS Instead, use pull-up transistor that is always ON In CMOS, use a pMOS that is always ON Ratio issue Make pMOS about 1⁄4 effective strength of pulldown network Pseudo-nMOS Gates Design for unit current on output to compare with unit inverter. pMOS fights nMOS Pseudo-nMOS Gates 4. PSEUDO NMOS 4.1. Pseudo NMOS Adder The design of a high-speed low-power I-bit full adder cell [7]. The main design objectives for this adder circuit are low power consumption and higher speed at low supply voltage. Using pseudo-NMOS [7], [8] together with two inverters this adder cell has been designed in CMOS process. As shown in fig (6).
The gates were implemented using CMOS, NMOS pass transistor, PMOS pass transistor, transmission gate, pseudo-NMOS, dynamic, and domino logic technologies. Additionally, the single node yields the ...Pseudo nMOS Load Choices Better than just grounding the pMOS load, we can: Make the pMOS current track the nMOS device (to reduce the variations in the ratio of the currents as the fab process changes) by using a circuit trick - a current mirror.…

The difference between the pseudo-NMOS and the CMOS inverter in regards to timing is that there is a significant PMOS current that exists when the NMOS is on. This is the case for t pHL in our NOR. Thus, we can modify equation 5.21 from the reader to get the following: t organic material in oil mostly comes from In LTSPICE, I've built a pseudo-NMOS inverter. 1) I've a initial guess for Wn value of NMOS.
