Abstract
An electronic inductor circuit comprises a pair of cascoded Darlington bipolar or MOSFET transistors, configured such that the impedance presented by the collector (drain) of the top transistor of the electronic inductor is increased, relative to the other resistive components in the electronic inductor circuit and DAA. The impedance is increased to a magnitude such that small fluctuations in the collector (drain) impedance do not vary the over-all electronic inductor circuit impedance. Therefore, as heat generated by the circuit causes the impedance of the transistor in the electronic inductor to change, the impedance change does not adversely affect over-all modem circuit performance.
