It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...
Although 5V-powered logic isstill common in many applications,most FPGAs support interfacelevels of 3.3V and lower. When youconnect an FPGA to higher voltagelevels, the FPGA’s application ...
