| Abstract: | A novel OTA-based active filter derived from the active-RC state variable circuit is presented. The filter
can simutaneously give the lowpass, bandpass and highpass filtering functions from the different outputs on a
single building block. The circuit is linearly electronically tunable, and is low sensitive respecting to g_m varia-
tion. Morever, the circuit requires only four OTA components and two capacitors, the minimum number of
components. |
