A new MOSFET-capacitor integrator is presented. The new circuit makes use of the balanced-time-constant (BTC) active-

differential integrator. It is shown that the new integrator may not require the use of balanced-output operational amplifier. Moreover, it may function as an inverting or a noninverting integrator. The application of the new integrator in the implementation of MOSFET-capacitor biquad filters is discussed.
