You can set 1 10 100 1000 times magnification programmable amplifier
Description: The Jiu zoom magnification circuit operates as an inverted feedback circuit, where the voltage division ratio is determined by a factor ranging from 2 to 5. This ratio establishes the partial pressure ratio, which can be selected through an external signal. For instance, to achieve a partial pressure ratio of 1/10, a resistor divider circuit with a configuration of 90 kΩ and 10 kΩ can be employed. Each magnification setting necessitates specific calculations for the circuit diagram parameters. The chosen resistor array is designed to adapt to the resistor divider, ensuring high precision in applications. The circuit incorporates an input protection mechanism, which includes components such as D- and Dz, allowing for operation without compromising the integrity of the feedback circuit. To adjust the feedback circuit's division ratio for variable gain, a small input bias current is essential. The circuit utilizes a FET input type operational amplifier, which functions as a variable gain DC amplifier and requires careful offset adjustment throughout its operation.
The Jiu zoom magnification circuit exemplifies a sophisticated design that leverages inverted feedback mechanisms to achieve variable gain based on external signal inputs. The voltage division ratio, set between 2 and 5, allows for flexibility in applications requiring different levels of magnification. The resistor divider configuration, specifically using a 90 kΩ and 10 kΩ resistor pair, is critical for establishing the desired partial pressure ratio. This ratio can be finely tuned by adjusting the resistor values, which directly influence the output characteristics of the circuit.
In high-precision applications, the selection of the resistor array is paramount, as it must ensure minimal deviation from the expected values. The inclusion of input protection components, such as diodes D- and Dz, enhances the circuit's reliability, safeguarding it against potential overvoltage conditions and ensuring stable operation during surgical procedures.
Moreover, the circuit's ability to modify the feedback division ratio is facilitated by the introduction of a small input bias current. This feature is particularly important for maintaining the integrity of the gain settings across various operational scenarios. The use of a FET input type operational amplifier is a strategic choice, as it provides high input impedance and low noise characteristics, essential for maintaining signal fidelity in variable gain applications. The requirement for offset adjustment underscores the need for precision in the overall circuit design, ensuring that the output remains consistent and accurate throughout its operational range.
Overall, the Jiu zoom magnification circuit presents a well-engineered solution for applications demanding variable gain and high precision, with robust design elements that enhance its functionality and reliability.
