Diode less Rectifier Circuit Diagram . It`s common knowledge that when working with single-supply op amps,
implementing simple functions in a bipolar signal environment can be
difficult. Sometimes additional op amps and other electronic components
are required. Taking that into consideration, can any advantage be
attained from this mode The answer lies in this simple circuit (A).
Requiring no diodes, the circuit is a high-precision full-wave rectifier
with a liigli-frequency limitation equalling that of the op amps
themselves. Look at the circuit`s timing diagram (B) to see the
principle of operation. The first amplifier rectifies negative input
levels with an inverting gain of 2 and turns positive levels to zero .
The second amp, a noninverting summing amplifier, adds the inverted
negative signal from the first amplifier to the original input signal.
The net result is the traditional waveform produced by full-wave
rectification. In spite of the limitation on the input signal amplitude
(it must be less than VCCJZ), this circuit can be useful in a variety of
setups.
