4 CONCLUSIONS
A new circuit topology for realizing inverting and
noninverting half wave rectifiers is presented. Only
one VCII, two diodes and a single resistor are used.
The circuit gain can be adjusted by resistor value. The
input signal is in current form and rectified output
signal is in voltage form which is provided in low
impedance Z port of VCII

. Therefore, no voltage
buffer is required for practical application. Simple
implementation, high frequency performance, low
power consumption and low linearity error are main
advantages of the proposed half wave rectifier
topology.
