Choosing Logic Analyzers: Often Overlooked Probes

Choosing Logic Analyzers: Often Overlooked Probes

Abstract There are numerous articles introducing the performance of logic analyzers, but few specifically discuss the measurement probes for logic analyzers. It is important to note that the instrument itself is only part of the measurement system; the choice of measurement probes and their manufacturing processes are also crucial. Many times, we use the most … Read more

Linear Accuracy of Resistor DAC

Linear Accuracy of Resistor DAC

1. Introduction Recently, I built an R2R ladder resistor DAC circuit using resistors with a precision of one thousandth. Through testing, the circuit achieved a linear accuracy of 12 bits. Now, I ponder a question: if I reduce the order of R2R, for example to 12 bits, what would its linear accuracy be? Below, I … Read more
