95IEEE 1355 — IEEE 1355, IEC 14575, or ISO 14575 is a data communications standard, the IEEE Standard for Heterogeneous Interconnect (HIC). It is a low cost, low latency, scalable serial interconnection system, originally intended for communication between… …
96Electronic filter topology — An elementary filter topology introduces a capacitor into the feedback path of an op amp to achieve an unbalanced active implementation of a low pass transfer function Electronic filter topology defines electronic filter circuits without taking… …
97Bipolar transistor biasing — Bipolar transistor amplifiers must be properly biased to operate correctly. In circuits made with individual devices (discrete circuits), biasing networks consisting of resistors are commonly employed. Much more elaborate biasing arrangements are …
98JESD204 — JEDEC JESD204A (2008) is a new industry standard for the interconnection of digital to analog converter (DAC or D to A) or analog to digital converter (abbreviated ADC, A/D or A to D) and logic devices which supports the concept of multiple… …
