Electronically Tunable Current-Mode Quadrature Oscillator Using Single MCDTA

Electronically Tunable Current-Mode Quadrature Oscillator Using Single MCDTA

This paper presents a modified current differencing transconductance amlpifier (MCDTA) and the MCDTA based quadrature oscillator. The oscillator is current-mode and provides current output from high output impedance terminals. The circuit uses only one MCDTA and two grounded capacitors, and is easy...
