The simple CMOS negative capacitance with improved frequency response

The negative capacitance circuits are very interesting analog building blocks with many possible applications like the compensation of undesired parasitic capacitance, bandwidth enhancement of amplifiers, equalization filters design without passive inductors, etc. This paper presents a method for improving and controlling CMOS floating negative capacitance frequency response. Since the negative capacitance is generated by the simple and known negative impedance converter (NIC), the proposed method is applicable for negative inductance and resistance also. The proposed method is simulated and verified using standard 0.35μm and 0.18μm CMOS processes.
