signal path through the input network and a cancellation path through the cancellation circuit 208 second the impedance network i e resistors r 1 r 2 that carries the positive portion of the input signal is coupled to the negative input terminal of the transconductance circuit 104 while the impedance network i e resistors r 2 r 4 that carries the negative portion of the input signal is coupled to the positive input terminal of the transconductance circuit 104 this arrangement allows the cancellation circuit 308 to remove or subtract a cancellation current from the input terminals of the transconductance circuit 104 instead of directly clamping and this arrangement allows the distortion introduced by cancellation circuit 208 to increase inversely with the control voltage vcntl or gain control signal gc thus the thd decreases proportionally with an increasing gain control signal allowing for a wider gain range than amplifier 100 i e a nearly 20 db increase turning to fig3 another example of a variable gain amplifier 300 can be seen amplifier 300 is similar to amplifier 200 but amplifier 300 also includes current to voltage converter 302 and 304 each of these voltage to current converters 302 and 304.
