Clock Domain Crossing Techniques & Synchronizers - EDN
Sep 30, 2014 · In general, a conventional two flip-flop synchronizer (2-FF) is used for synchronizing a single bit level signal. As shown in Figure 1 and Figure 2 , flip flop A and B1 are operating in asynchronous clock domain. There is probability that while sampling the input B1-d by flip flop B1 in CLK_B clock domain, output B1-q may go into metastable state.
Memory fault models and testing - EDN
Jun 29, 2015 · Read destructive Faults (RDFs): A read operation is performed to the cell causes inversion of the value in the cell and returns the incorrect value. There are two types of read destructive faults: 1) Memory cell in state 0, read 0 on it. Cell becomes 1. Denoted as. 2) Memory cell in state 1, read 1 on it.

Linearized portable anemometer with thermostated Darlington pair
Sep 19, 2022 · Figure 1 Power dissipated versus air flow of TO92 held at a constant 31 o C above ambient (Pw = 31/ZT).. Figure 2 shows a practical portable thermostat circuit to achieve and maintain this delta-T utilizing a Darlington transistor pair (Q1 and Q2) to compensate for ambient temperature and convert the resulting nonlinear Pw curve into a …
IP partnerships stir the world of FPGA chiplets - EDN
Aug 29, 2023 · IP partnerships stir the world of FPGA chiplets. The tie-ups between IP suppliers of embedded FPGA (eFPGA) and UCIe chiplets mark a new era of FPGA chiplet integration in die-to-die connectivity. Chiplets are rapidly being adopted as heterogeneous multi-chip solutions to enable lower latency, higher bandwidth, and lower cost solutions than ...
Simple circuits reduce regulator noise floor - EDN
Oct 15, 2013 · The LM317 is an excellent noise source for testing the regulator circuits as the noise was fairly flat over the 120 to 50,000-Hz test frequency range. It drives the test circuits well and the noise is constant enough with load to make the testing valid. Figure 4 shows the test circuit and its components.
