Abstract
Aspects of the present disclosure provide techniques and apparatus for current-mode analog signal filtering. An example filter circuit generally includes a current-mode amplifier. The current-mode amplifier includes a first amplifier including an input and an output; a first inverter including an input coupled to the output of the first amplifier and including an output coupled to a first feedback path, the first feedback path being coupled to a first input of the filter circuit; and a second inverter including an input coupled to the output of the first amplifier.
Claims29
A filter circuit, comprising:
- a current-mode amplifier comprising:
- a first amplifier including an input and an output;
