Description: The realization of a type 03 receive filter is achieved using eight OP-08 operational amplifiers. The response curve indicates that the requirement for greater than 30 dB attenuation in the stop band has been satisfied. Furthermore, the noise performance has been measured to be less than 0 dBRn. A notable feature of the OP-08 is its low maximum supply current of 600 µA. Consequently, the total supply current for all eight operational amplifiers is only 4 mA.
The type 03 receive filter designed with eight OP-08 operational amplifiers offers significant advantages in terms of performance and efficiency. These operational amplifiers are configured to achieve a high level of attenuation in the stop band, which is crucial for effective filtering in communication systems. The specified attenuation of greater than 30 dB ensures that unwanted signals are significantly suppressed, allowing for a clearer reception of the desired signal.
The noise performance metric, measured at less than 0 dBRn, indicates that the filter operates with minimal noise interference. This characteristic is essential in applications where signal integrity is paramount, such as in audio processing or RF communications. The low noise figure contributes to the overall quality of the received signal, enhancing the system's performance.
The OP-08 operational amplifier is particularly noted for its low supply current of 600 µA, which is a critical factor in power-sensitive applications. With eight of these amplifiers in use, the total supply current requirement is only 4 mA. This low power consumption is advantageous for battery-operated devices and helps to extend operational life without sacrificing performance.
In summary, the type 03 receive filter utilizing OP-08 operational amplifiers demonstrates an effective design that meets stringent requirements for attenuation and noise performance while maintaining low power consumption. This makes it suitable for a wide range of applications in electronic communication systems.The above realization of a type 03 receive filter is accomplished using eight OP-OS"s. As can be seen from the response curve, the >30dB attenuation in the stop band requirement has been met. In addition, the noise performance of
