when the threshold voltage of NMOS fluctuates in the range of 0.53V to 0.69V, and threshold voltage of PMOS fluctuates in the range of -0.47V to -0.67V, the CC-MCML technique is able to suppress ΔVwithin only
The difference between the threshold voltages Vt of pMOS and nMOS transistors is a critical issue in the low-voltage operation of CMOS circuits. The pMOSMOS Vt balancing profit is analyzed in terms of subthreshold leakage current and the performance of CMOS LSIs and the minimum supply voltage of...
One of the most important physical parameters of a MOSFET is its threshold voltage V th , defined as the gate voltage at which the device starts to turn on. The accurate modeling of threshold voltage is import
However, the boost converter only operates in PWM mode, which limits the efficiency of the converter at light loads. Ref. [30] added an auxiliary power PMOS to the staged start to further reduce the converter start-up voltage, but increased the complexity of the control circuit. On the ...
According to a first embodiment of the invention, a CMOS transistor pair (one PMOS and NMOS transistor) of a CMOS circuit is fabricated such that the PMOS transistor has a first threshold voltage and the NMOS transistor has a second threshold voltage which is different in magnitude from the fi...
To maximize the current efficiency, novel biasing scheme using series capacitor between two input transconductors is proposed so that the current efficiency of NMOS and PMOS transistors are individually maximized. In order to correct random source voltage variation, the switching threshold range is ...
1. A method of fabricating a CMOS device of the type that comprises substantially complementary-threshold-voltage NMOS and PMOS transistors which include silicide-on-doped polysilicon gates, said method comprising the steps of forming a polysilicon layer on a substrate, ...
effect of self-reverse-bias series-connected transistors. However, the transistor impacts the switching speed due to a nonzero voltage drop across the gated-Vdd transistor between the supply rails and the “virtual Gnd” for NMOS gated Vdd (Figure 7.11) or the “virtual Vdd” for PMOS gated-...
In a CMOS implementation of NCL dynamic gates, the set block is a pull-down network of NMOS transistors, de- rived from the equations in Table 2 for each of the 27 NCL gates. On the other hand, the reset block is always a series chain of PMOS transistors consisting of one transistor...
An erase operation for non-volatile memory includes first and second phases. The first phase applies a series of voltage pulses to a substrate, where each erase pulse is followed by
