\( \newcommand\): Rectifier with gain. Computer Simulation A Multisim simulation of the circuit shown in Figure \(\PageIndex\): Output waveforms of precision rectifier. 7.2.1: Peak Detector One variation on the basic half-wave rectifier is the peak detector. This circuit will produce an output that is equal to the peak value of the input signal. This can be configured for either positive or negative peaks. The output of a peak detector can be used for instrumentation or measurement applications. It can also be thought of as an analog pulse stretcher. A simple positive peak detector is shown in Figure \(\PageIndex = 2.5 mV/\mu s \nonumber \] This is a very slow slew rate! If FET input devices are used, the effective discharge resistance can be very high, thus lowering the requirement for \(C\). For typical applications, \(C\) would be many times smaller than the value used here. For long discharge times, high quality capacitors must be used, as their internal leakage will place the upper limit on discharge resistance. Example \(\PageIndex\). 7.2.2: Precision Full-Wave Rectifier A full-wave rectifier has the input/output characteristic shown in Figure \(\PageIndex\): Power amplifier overload detector.

Students will first simulate and build the rectifier to gain an understanding of the purpose of a rectifier. Then, students will use LabVIEW to explore the individual components of the rectifier in order to visualize and understand how these components limit its operating range. Advanced students can explore ways to overcome the threshold voltage limit when using diodes in a rectifier or learn more about programming practices and user-friendliness. Introduction A rectifier is a diode circuit that converts an alternating current (AC) waveform into a waveform that has constant polarity (also sometimes called a direct current or DC waveform), either always negative or always positive depending on the direction of the diodes. There are two major classifications of rectifiers, half-wave and full-wave rectifiers. Half-wave rectifiers are so called because they only pass through one polarity of the circuit while the opposite polarity is removed. Full-wave rectifiers reproduce the whole waveform, but with on...
