Transconductors are commonly used as active elements in high-frequency (HF) filters,
amplifiers, mixers, and oscillators. This paper reviews transconductor design by focusing on …

A new method of analog filter design is proposed where nonlinear active components are a
natural part of a filter realizing an overall linear transfer function. This approach to design is …

Fuzzy logic has virtually exploded over the landscape of emerging technologies, becoming
an integral part of myriad applications and a standard tool for engineers. Until recently, most …

Two new multiple-mode (including voltage, current, transconductance, and transresistance
modes) OTA-C universal biquad filters are proposed. The first proposed circuit uses only …

At depths above 1000 m, the currents of the southwestern Pacific are traditionally
considered to be dominated by the broad westward flow of the South Equatorial Current …

A linear, fully balanced, voltage-tunable CMOS operational transconductance amplifier
(OTA) with large dc gain and wide bandwidth is described. The approach uses a two …

None of the recently reported voltage-mode versatile filters are digitally programmable for
applications like the easy addition of current-mode filtering signals to do the synthesis. None …

None of the previously reported third-order and fourth-order operational transconductance
amplifier and capacitor (OTA-C) elliptic filter structures use the minimum number of active …

This work presents a new general synthesis method for high-order current-mode OTA-C
(operational transconductance amplifiers and capacitor) filters. The method is based on the …

A 4-MHz, fifth-order elliptic low-pass Gm-C filter is described whose characteristics are tuned
by an on-chip automatic tuning circuit. The tuning circuit uses only one integrator as the …
