Abstract:
An exemplary negative impedance converting circuit for functioning as a voltage buffer and/or negating the impedance of a connected load. The negative impedance converting circuit includes inputs, outputs, a first transconductance stage and a second transconductance stage. The transconductance gain value of the first transconductance stage is greater than a transconductance gain value of the second transconductance stage. Exemplary embodiments of a reference voltage buffer using the negative impedance converting circuit are also described.
