How does the leakage current in a CE configuration compare to that in a CB configuration____________that in CB arrangement?
Show answer Hide answer
Answer: A. more than
Explanation
Leakage current in a common emitter configuration is designated as ICEO and includes multiplied collector-base leakage. The common base leakage current (ICBO) is amplified by the transistor's beta factor in the common emitter setup. Therefore, the resulting leakage current in a common emitter arrangement is significantly more than in a common base setup. Minority carrier leakage currents flow across reverse-biased semiconductor junctions even in the absence of input signals. Temperature increases cause semiconductor leakage currents to rise exponentially, impacting bias stability in amplifiers. Circuit designers incorporate biasing compensation networks to counteract the effects of thermal leakage currents.
Less than would incorrectly imply that common emitter leakage is smaller than common base leakage current. The same as ignores the beta multiplication factor that makes common emitter leakage substantially larger. None of the above is incorrect because more than accurately compares the two leakage current magnitudes.
