| Summary: | Nowadays, current mode devices are used as active elements at the circuits that work at high frequencies. A novel integrated CMOS based the operational floating current conveyor (OFCC) is proposed. OFCC is a five port general purpose analog building block which combines all the features of different current mode devices such as the second generation current conveyor (CCII), the current feedback operational amplifier (CFA), and the operational floating conveyor (OFC). The OFFC is modeled and simulated using UMC 130nm technology kit in Cadence and the supply voltage of the proposed OFCC is 1.2V. Non-inverting voltage amplifier, current mode instrumentation amplifier (CMIA), universal filter and electrocardiogram read out circuit (ECG) are the applications based on OFCC that are designed to check the circuit’s validity. ECG is used in diagnosing heart diseases. It is designed as integration between current-mode instrumentation amplifiers (CMIA) and low pass filter (LPF). Normal heart behavior can be identified simply by normal ECG that consists of signal while heart disorder can be recognized by having differences in the features of their corresponding ECG waveform. The main advantage of the proposed OFCC that it provides a wide bandwidth compared to other work. In addition, the applications based on OFCC shows good results compared to others. |
