The circuit design involves two identical circuits whose outputs are connected in parallel, facilitating a combined output. The negative output from the first circuit is connected to the negative output of the second circuit, while the positive output from the first circuit connects to the positive output of the second circuit. This configuration allows for simultaneous readings from a common point, which is the junction where the two circuits are interconnected.
A ground wire is taken from the circuit, specifically positioned between two large electrolytic capacitors, ensuring a stable reference point for the circuit's operation. The use of two 100 microfarads polarized electrolytic capacitors provides significant filtering and stabilization of the power supply, which is crucial for maintaining the performance of the circuit.
The circuit also incorporates four ceramic disk capacitors rated at 0.1 microfarads. These capacitors serve as high-frequency bypass components, effectively filtering out noise and ensuring stable operation across the circuit's frequency range.
Four germanium diodes, specifically the 1N34A type, are utilized in the design. These diodes are known for their low forward voltage drop and are suitable for applications requiring high sensitivity. The 1N34A diodes have a peak reverse voltage rating of 75 volts, making them appropriate for various low-power applications. When selecting diodes, it is essential to verify their specifications to ensure compatibility with the intended circuit design.
For sourcing components, the diodes can be found at Mouser Electronics, which provides a reliable supply. Additional resources, such as datasheets and specifications, are available online to assist in confirming the characteristics of the 1N34A diodes and comparing them with other types of germanium diodes. Proper selection and implementation of these components are critical to achieving the desired performance and reliability of the overall circuit.If you decide to use 2 circuits, i just connect their outputs together...neg output from first circuit to neg output of second circuit & pos output from first circuit to pos output of second circuit.
