File Size : 116 KB Manufacturer:AVAGO Description: The amplifiers are intended for use directly coupled, as shown in Fig. 8. The seventh stage in an untuned cascade will be giving virtually full output on noise. Noise may be reduced by inserting a single tuned circuit in the chain. As there is a large mismatch between stages a simple parallel or series circuit cannot be used. This choice of network is also controlled by the need to avoid distorting the logarithmic law: the network must give unity voltage transfer at resonance. A suitable network is shown in Fig. 9. The value of C1 must be chosen so that at resonance its admittance equals the total loss conductance across the tuned circuit. Resistor R1 may be introduced to improve the symmetry of filter response, providing other values are adjusted for unity gain at resonance. A single capacitor may not be suitable for decoupling the output line if many stages and fast rise times are required. Values of supply line decoupling capacitor required for untuned cascades are given below. Smaller values can be used in high frequency tuned cascades.
