Whenever the external switch changes channels, the DMM input is connected to a different voltage or resistance. Each time this process happens, the DMM, interacting with the source, behaves as an RC circuit with a settling time that corresponds to: ...
The present invention discloses a circuit for settling DC offset and controlling RC time-constant in a direct conversion receiver. The circuit includes a variable resistive unit for providing a continuously or non-continuously variable resistance in the direct conversion receiver. The variable resistive...
Method and apparatus for optical disk recording capable of reducing settling time and generating an accurate channel clock signal An optical disk recording apparatus includes a first comparator, a second comparator, a third comparator, a selection circuit, a control voltage generator, a voltage control...
settling time; therefore some optimization is required in the actual circuit to get best performance. When the pulse generator output “A” goes above 0V, D1begins to conduct, and D2/D3are reversed biased. The “0V” region of the signal “B” at the input of the device to be tested...
a single pole RC filter. STC finds the time it takes (ts) for the output voltage to respond to a step input voltage (Vstep) and settle to within a specified fraction (Accu) of the final value. Three additional circuit parameters are found: time constant, cutoff frequency, and rise time...
2.2 Settling Time of the ADC Input Circuit Because the equivalent input tracking circuit of the ADC is an RC circuit, we will calculate settling time in terms of time constants. It is useful to specify settling time as the number of time constants it will take for an accuracy specified as...
According to the above objects of the present invention, there is provided a circuit for settling DC offset and controlling RC time-constant in a direct conversion receiver. The circuit includes a variable resistive unit for providing a continuously or non-continuously variable resistance. The variabl...
tor is very fast, the fall time and overshoot of the output waveform become functions of the diodes’ speed and recovery time, as well as of the parasitic capacitance and inductance of the printed circuit board (PCB) on which the FBPG is built. In other words, the designer should pick ...
24.A method for reducing the settling time of a line driver circuit, comprising:buffering an input signal to produce an output signal using an amplifier configured in a negative feedback loop;allowing said amplifier to presettle before transmitting said output signal onto a bus line;connecting sai...
This configuration reduces the settling time of the line driver by substantially eliminating the effect of the switch resistance on the RC time constant. The line driver also comprises offset cancellation and presettle circuits that improve the integrity of the output signal and reduce the power ...
