Abstract:
A precision fullwave rectifier, the precision fullwave rectifier used in communication systems and non-linear signal processors, the precision fullwave rectifier comprising:an input part receiving a first alternating current input signal and a second alternating current input between which a phase difference of about 180.degree. exists, the input part generating a first current and a fourth current proportional to the first alternating current input signal, the input part generating a second current and a third current proportional to the second alternating current input signal;a first current subtractor outputting a fifth current by subtracting the second current from the first current;a second current subtractor outputting a sixth current by subtracting the fourth current from the third current; andan output part transforming and generate an wave-rectified output voltage by adding the fifth current to the sixth current.
