Design of Comparator and Binary Amplitude Shift Keying Modulator using CCCII

A novel circuit is proposed for designing a Second Generation Current Controlled Conveyor (CCCII) based Comparator and Binary Amplitude Shift Keying (BASK) modulator. Comparators find applications in almost every field related to the electronics and BASK find applications in the areas of wireless communications, RFID systems, Infrared (IR) remote controls, Digital Audio Broadcasting, Data Communication over Power Lines, Testing and Prototyping, Control Systems and Industrial Automation. The two topologies are designed using single CCCII and is tested using Cadence Virtuoso simulator tool with 45 nm technology files and found satisfactory. Delay and power dissipation are also calculated for the proposed topologies.
