MX045-18.432MHZ on stock (1) Equalizer amplifier design The equalizer amplifier consists of a voltage follower with a voltage gain of o dB. To compensate for the frequency characteristics, externally connect L, C, and R as shown in Fig. 26. Operation in this case is as follows: Assigning the input to vi and the output to vo, (Rl/Z + 1) (vi + vin) = vo Assuming imaginary short state, if vin 0, then: Av = vo/vi = Rl/Z + 1 If the application of pin 20 is as shown in Fig. 27, it can be used as a voltage amplifier. One point that requires caution, however, is the dynamic range of the equalizer amplifier. In short, the bleeder resistance ratio must be designed so that signals are not amplified excessively, and so that the leading edge voltage of the video signal sync signal is not too high or too low. In other words, the design must be such that the sync signal voltage does not change. | | Min | Typ | Max | | DC current gain - Kollektor-Basis-Stromverhaltn - VCE = 1 V, - IC = 100 mA BC807 - VCE = 1 V, - IC = 500 mA BC808 | 1S hFE hFE | 100 40 | | 600 | | Group -16 - VCE = 1 V, - IC = 100 mA Group -25 Group -40 | hFE hFE hFE | 100 160 250 | 160 250 400 | 250 400 600 | | | | | |
