Design of frequency generator and amplifier level converter using 300nm CMOS technology for electro capacitive cancer therapy (ECCT) standard operation mode system

Electro capacitive cancer therapy (ECCT) system are constructed by six sub-systems, in this paper presented design and simulation for two sub-system in ECCT namely frequency generator and amplifier level converter. Design of two sub-system become first study for ECCT system can be applying to the IC technology. Design process begins with understand ECCT standard operation mode signal specification like input signal voltage, output signal voltage, form and frequency. Then using ring oscillator, negative clamper biased, two stage operational amplifier (op amp) circuits that estimated can produce those signal specification and layout them based on BSIM 3.1 MOSFET model using 300nm CMOS technology. Simulation result show that the system layout can produce 19Vpp, 100 kHz and asymmetric output signal from 5 volt DC input signal.
