Low voltage Low Power Fully Differential Buffer
In this letter a useful CMOS fully-differential buffer topology is presented. The proposed solution, performing the common mode feedback (CMFB) operation, shows a rail-to-rail characteristic, so it is particularly suitable for low-voltage (± 0.75V) low-power (<400 μW) applications. The simulated results have shown excellent general performance, evaluated in terms of suitable figures of merit (F...
متن کاملFigures of Merit for Best - FirstProbabilistic Chart
Best-rst parsing methods for natural language try to parse ee-ciently by considering the most likely constituents rst. Some gure of merit is needed by which to compare the likelihood of constituents, and the choice of this gure has a substantial impact on the eeciency of the parser. While several parsers described in the literature have used such techniques, there is no published data on their ...
متن کاملFigures of merit for color scanners
In the design and evaluation of color scanners and cameras, it is useful to have a single figure of merit that closely agrees with perceived color accuracy. In the past, several measures of goodness for color scanning filters have been proposed to fulfil such a requirement. Most of the proposed measures have had shortcomings in that they are either based on error metrics in color spaces that ar...
متن کاملFigures of merit in high-frequency and high-power GaN HEMTs
The most important metrics for the high-frequency and high-power performance of microwave transistors are the cut-off frequency fT , and the Johnson figure of merit FoMJohnson. We have simulated a state-of-the-art, high-frequency and high-power GaN HEMT using our full band Cellular Monte Carlo (CMC) simulator, in order to study the RF performance and compare different methods to obtain such met...
متن کاملA Novel Low Input Impedance Low Power Fully Differential Current Buffer with ±0.65V Supply Voltage and high bandwidth of 520MHz
A new fully differential (FD) low input impedance CMOS current buffer with low voltage, and low power operation is presented. The low input impedance is achieved by remarkable reduction of the input node voltage swing using a novel double feedback scheme. Some advantages of the proposed double feedback scheme over the conventional (either positive or negative) feedback techniques are: lower inp...
