Abstract :
A novel variable-phase inverting amplifier is given. The proposed inverter has an adjustable phase which depends on the unity-gain bandwidth of only one of the two o.a.s employed in the circuit. Application of the inverter for phase correction in two-integrator loop filters is discussed.
