could remarkably boost its output resistance without requiring increased power supply.Simulation with 0.6μm CMOS process models shows that the output resistance of the novel current source can reach the order of 10~9Ω with a 1.04GHz bandwidth and only 10.6ppm/℃ in the range of -40～145℃....
Although a Class A output stage is a constantresistive load, a Class AB2 output stage heavily loads the driver stage when drawing grid current, and its driver stage would need verylow output resistanceand be able to source significant current to drive this load without distortion. ...
No input to an IC input is to be left unconnected (referred to asfloating input). If an input to an IC is not required, then it must be tied to logic level (0 or 1). This is usually achieved by connecting a high-resistancevalue resistor(typically 10 to 100 kΩ in value) between...
Example 1.1 The output resistance of a signal source, although inevitable, is an imperfection that limits the ability of the source to deliver its full signal strength to a load. To see this point more clearly, consider the signal source when connecte...
Linear— The block represents the output as a voltage source plus series resistance and parallel capacitance, as shown in the following figure. The value you specify for theOutput resistanceparameter is assigned to the series resistance, and the capacitance values are determined by matching the RC ...
Peaking occurs due to inductor components and capacitance components of the FPC. However, by application of voltage to the variable voltage source, the gate voltage value of the FET is adjusted to be an optimal value, whereby the peaking is suppressed by the on-resistance of the FET. 展开 ...
The numerator represents attenuation factors for the output power:αis related to the parasitic loss in the passive elements in the output matching network, whileβrepresents the loss due to theparasitic resistanceof the switches in series with the bottom-plates of the capacitors in the array. The...
and it is claimed that this is responsible for the excellent midrange detail in this breed of amplifiers. However, a more prosaic explanation is that voice coil inductance causes loudspeaker impedance to rise above 250Hz, and that when driven from a source resistance of half the loudspeaker’s ...
In order to achieve load-independent constant-voltage or constant-current output from the AC source to the equivalent resistance, the design of compensation circuits is divided into three sections as displayed in Figure 3: source-side conversion circuits, load-side conversion circuits, and LCT conver...
