Abstract: Each cascaded amplifier stage comprises two input transistors (118, 120) and two control transistors (110, 112) respectively supplied with bias voltage V and bias current I. The differential current flowing through transistors (118, 120) is amplified by each stage. By connecting diode loads, (D1 D2); (D3, D4) and (D5, D6) in the connections between the emitters of transistors (118 min , 120 min ) and the base collector connections of transistors (110 min /112 min ) and (120 min /110) etc., the amplification in each stage is increased so that the differential current is amplified at a higher rate than the proportion of I2:I1; I3:I2 etc.
