Abstract :
A grounded-capacitor single-resistor tunable two-operational amplifier (OA) noninverting integrator network realisation and the compensation design for its quality-factor (Q) at high frequency are presented. The novelty of the proposed design is that it is independent of the tuning of the time constant (T0) and precise high quality (Q to infinity ) performance can be derived up to the bandwidth of the OA devices.
