In digital electronics, the power–delay product (PDP) is a figure of merit correlated with the energy efficiency of a logic gate or logic family. [1] Also known as switching energy , it is the product of power consumption P (averaged over a switching event) times the input–output delay or duration of the switching event D . [ 1 ]
From here, it can be easily seen that adding more inverters to the chain increases the total gate delay, reducing the frequency of oscillation. The ring oscillator is a member of the class of time-delay oscillators. A time-delay oscillator consists of an inverting amplifier with a delay element between the amplifier output and its input.
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
The formula is not exact however, as many modern chips are not implemented using 100% CMOS, ... Power gating; Power–delay product (PDP) Energy–delay product (EDP)
In data communications, the bandwidth-delay product is the product of a data link's capacity (in bits per second) and its round-trip delay time (in seconds). [1] The result, an amount of data measured in bits (or bytes), is equivalent to the maximum amount of data on the network circuit at any given time, i.e., data that has been transmitted but not yet acknowledged.
A gate is replaced by a logically equivalent but differently-sized cell so that delay of the gate is changed. Because increasing the gate size also increases power dissipation, gate-upsizing is only used when power saved by glitch removal is more than the power dissipation due to the increase in size.
The power delay profile (PDP) gives the intensity of a signal received through a multipath channel as a function of time delay. The time delay is the difference in travel time between multipath arrivals. The abscissa is in units of time and the ordinate is usually in decibels.
Top: source, bottom: drain, left: gate, right: bulk. Voltages that lead to channel formation are not shown. In field-effect transistors (FETs), depletion mode and enhancement mode are two major transistor types, corresponding to whether the transistor is in an on state or an off state at zero gate–source voltage.
