Performance analysis of radix-4 adders Linköping University Post Print

... In this work, we design a radix-4 FA instead of the more common radix-2 FA. The radix-4 FA is based on internal carry look-ahead to reduce the carry propagation path in an adder since that path is critical [3]. The main disadvantage of this architecture is a slight increase in transistor count. With ...

Opto-isolator



In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 10 kV/μs.A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
