Conventional rectifiers employing diodes can’t be used with low-amplitude signals. This Idea for Design describes a circuit using Analog Devices' AD844 op amps to create a mixed-mode precision ...
Figure 2 Unconventional rectifier with discrete circuit inverter still uses symmetry-setting resistors: R1 and R2. But now, just to break the monotony, regard Figure 3. Note the (shocking) absence of ...
It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected to the voltage-to-clamp-to rather than ...
Circuit performance parameters, precision, symmetry, and speed are good, mostly limited by the choice of op-amp and the precision of the R3/R5 resistor pair ratio. Their slightly non-unity ratio is ...
Similarly, another 2024 work introduced a voltage-mode full-wave rectifier employing single-IC OTAs, refining the design by achieving simultaneous positive and negative outputs without the need ...
The Precision Voltage Reference System is now available to back via Kickstarter with early bird pledges starting from just $14 and delivery expected to take place during February 2018.
