EL2082C
Current-Mode Multiplier
Applications Information
Contd
Frequency-setting resistors R are each effectively adjusted in value by an EL2082 to effect voltage-vari-
able tuning Two gain controls yields a linear frequency adjustment using one gives a square-root-of-
control voltage tuning The EL2082’s could be placed in series with the integrator capacitors instead to
yield a tuning proportional to 1Vg
The next circuit is one of a new class of ‘‘CCII’’ filters that use the current-conveyor element Basic
information is available in the April 1991 volume 38 number 4 edition of the IEEE Transactions on
Circuits and Systems journal pages 456 through 461 of the article ‘‘The Single CCII Biquads with
High-Input Impedance’’ by Shen-Iuan Liu and Hen-Wai Tsao
fO e 160 kHz
‘‘CCII’’ Class Filter
2082 – 24
This interesting filter uses the current output of the EL2082 to generate a bandpass voltage output and
the intermediate node provides a second-order low-pass filter output Both outputs should be buffered
so as not to warp characteristics although the VIN of the next EL2082 can be driven directly in the case
of cascaded filters The VGAIN input acts as a Q and peaking adjust point around the nominal 1V value
The resistor at IOUT could serve as the frequency trim and Q trimmed subsequently with VGAIN
Negative Components

replica of that impedance
