Abstract :
A linear current-mode integrator based upon the utilisation of a sinh-transconductor is described. The integrator and low-pass filter realisation at both transistor level and device level use a CCII and simple emitter-coupled pair based OTA to realise the required non-linear function. The resulting integrator has the advantage of DC stability. Simulation results are also included
