For a parallel version, the charging capacitance remains the same but the total capacitance increases by N times. In order to maintain the same sample rate, the clock period of the N-parallel circuit increases to N times the propagation delay of the original circuit. It makes the charging time prolongs N times. The supply voltage can be reduced ...
Sample times. Sample and hold. A sample-and-hold integrated circuit (Tesla MAC198) In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum ...
The method is often done in four steps, [3] but it can be reduced to three: Step 1. Write the KCL equations of the circuit. At each node of an electric circuit, write the currents coming into and out of the node. Take care, however, in the MNA method, the current of the independent voltage sources is taken from the "plus" to the "minus" (see ...
A programmer that writes implicitly parallel code does not need to worry about task division or process communication, focusing instead on the problem that his or her program is intended to solve. Implicit parallelism generally facilitates the design of parallel programs and therefore results in a substantial improvement of programmer productivity.
Another sample code fragment detects weddings among a flow of external "events" such as church bells ringing, the appearance of a man in a tuxedo or morning suit, a woman in a flowing white gown and rice flying through the air. A "complex" or "composite" event is what one infers from the individual simple events: a wedding is happening.
A paralleled amplifier configuration uses multiple amplifiers in parallel, i.e., two or more amplifiers operating in-phase into a common load. In this mode the available output current is doubled but the output voltage remains the same. The output impedance of the pair is now halved.
IF amplifiers in heterodyne receivers apply gain in a frequency band between the input radio frequency and output audio frequency or video frequency, often following one stage of RF amplifier. This allows most of the gain in the form of a fixed-frequency amplifier, simplifying tuning. Compare to its predecessor, the tuned RF receiver.
In electronics engineering, frequency compensation is a technique used in amplifiers, and especially in amplifiers employing negative feedback.It usually has two primary goals: To avoid the unintentional creation of positive feedback, which will cause the amplifier to oscillate, and to control overshoot and ringing in the amplifier's step response.
