A 0.35 mu m SiGe BiCMOS optical receiver with voltage-controlled transimpedance is presented. A variable-gain current amplifier using a BJT translinear loop is applied. A transimpedance dynamic range of 1554 (63.8 dB) with the largest transimpedance of 2.84 M Omega, a bandwidth up to 379 MHz, and a transimpedance bandwidth product up to 168 T Omega Hz are achieved.
