Current pumped voltage divided absorbor |
摘要 |
A two-terminal active network which simulates a low noise-temperature resistor is disclosed. In a preferred embodiment, a pair of operational amplifiers, each connected in the manner of a "current pump," comprises the active elements of the network. A resistive voltage divider network provides both positive and negative feedback to the operational amplifiers. Simulated resistors can be obtained with a wide range of equivalent resistance values and effective noise temperatures.
