Js. Rieh et al., SINGLE-FEEDBACK AND DUAL-FEEDBACK TRANSIMPEDANCE AMPLIFIERS IMPLEMENTED BY SIGE HBT TECHNOLOGY, IEEE microwave and guided wave letters, 8(2), 1998, pp. 63-65
Monolithically integrated SiGe/Si heterojunction bipolar transistor (H
BT) transimpedance amplifiers, with single-and dual-feedback configura
tions, have been designed, fabricated, and characterized, The single-f
eedback amplifier showed transimpedance gain and bandwidth of 45.2 dB
Omega and 3.2 GHz, respectively, The dual-feedback version exhibits im
proved gain and bandwidth of 47.4 dB Omega and 3.3 GHz, respectively,
Their performance characteristics are excellent in terms of their appl
ication in communication systems.
