摘　　要：A fast automatic power control（APC） circuit for a laser diode driver（LDD） has been implemented in a 0.6-μm BiCMOS process.The APC circuit adopts double-loops and variable-bandwidth techniques to achieve a turn- on time of 〈 400 /as for most kinds of TOSAs.Thus,it meets the small form-factor pluggable（SFP） agreement.Such techniques make a good tradeoff between stability,accuracy,turn-on time,noise and convenience.The measured results indicate that the APC circuit is suitable for SFP LDD.A fast automatic power control（APC） circuit for a laser diode driver（LDD） has been implemented in a 0.6-μm BiCMOS process.The APC circuit adopts double-loops and variable-bandwidth techniques to achieve a turn- on time of 〈 400 /as for most kinds of TOSAs.Thus,it meets the small form-factor pluggable（SFP） agreement.Such techniques make a good tradeoff between stability,accuracy,turn-on time,noise and convenience.The measured results indicate that the APC circuit is suitable for SFP LDD.
