Abstract
It is shown that utilizing the Nay-Budak circuit for the voltage-controlled resistor in the circuit proposed by D. Ghosh and D. Patranabis (see IEEE Trans. Instrum. Meas., vol.39, p.522-26, June 1990) increases the dynamic range by an order of magnitude while maintaining approximately the same accuracy as the original circuit throughout the improved range. The cost of this improvement is two op-amps and an increased potential for instability. However, a complete analysis shows that stability is easily obtained if a good-quality op-amp is employed for op-amp 2 in the circuit
