duty cycle jitter (tjit(duty))

The magnitude of the deviation in time duration between the primary threshold crossing and the secondary threshold crossing in a cycle over a random sample of cycles.

JESD65B, 9/03

duty cycle, power

The ratio of the power-on time duration per cycle to the total cycle time.

NOTE Power duty cycle is usually expressed as a percentage.

dynamic (read/write) memory

A volatile read/write memory in which the cells require the repetitive application of control signals generated inside or outside the integrated circuit to retain stored data. (Adapted from IEC 748‑2.)

NOTE 1 The words "read/write" may be omitted from the term when no misunderstanding is likely.

NOTE 2 Each repetitive application of the control signals is normally called a refresh operation or cycle.

NOTE 3 A dynamic memory can use static addressing or sensing circuits.

NOTE 4 Contrast with "static (read/write) memory".

dynamic phase offset (t(φ)dyn)

The incremental phase offset between the input reference clock and the feedback input signal of a phase-locked loop (PLL) resulting from modulation of the input reference clock.

References:

JESD65B, 9/03

dynamic random-access memory (DRAM)

A dynamic memory that permits access to any of its address locations in any desired sequence with similar access time to each location.

dynamic range (of a charge-transfer device)

The range of useful linear operation expressed as the ratio of the saturation input signal to the noise equivalent signal.
