AMPLIFICATORE A TRANS-IMPEDENZA PER INTERFACCIA OTTICO-ELETTRICA AD ALTA VELOCITÀ |
摘要 |
The differential trans-impedance amplifier uses trans-resistance(s) connected between the input nodes of a first differential amplifier, to implement a trans-impedance differential amplifier in a differential fashion and has two identical resistances, each connected between the photodiode and a respective DC voltage rail of a common bias network of the photodiode adapted to reverse bias the photodiode. The biasing resistances may be much larger than the trans-resistance(s) to prevent drawing any significant signal current from the photodiode. The amplifier may retain the advantages of a classical differential topology while effectively overcoming drawbacks that arise in high data rate applications. |
