WebAn example application of the current mirror is the transconductance op amp. The circuit is shown in Fig. 6. The circuit consists of an input diffamp and four Wilson current mirrors. For the analysis, we assume β→∞and VA→∞for each bjt so that the output current from each mirror is equal to the input current. WebSince β is the ratio of collector current to base current, and we have our load connected in series with the collector terminal of the transistor and our source connected in series with the base, the ratio of output current to input current is equal to beta. Thus, our current gain for this example amplifier is 100, or 40 dB. Voltage Gain ...
