The M02024 transimpedance amplifier (TIA) with

automatic gain control (AGC) is fabricated in

sub-micron CMOS for high performance. The

device targets a sensitivity of -29dBm, enabling

the use of low cost PIN diodes to meet the GPON

Class B+ standard.

In order to satisfy such high sensitivity and good

optical overload requirements, automatic gain

control (AGC) is implemented in the M02024. The

AGC monitors the output amplitude and auto-

matically reduces the TIA gain when the

photodiode current exceeds the AGC threshold,

maintaining the output at a constant level. With

an input overload capability greater than +6 dBm,

the AGC allows more than 35 dB of dynamic

range, providing a low-cost solution for longer-

reach 2.5 Gbps GPON/ATM/SONET systems that

formerly required an APD. For even greater sen-

sitivity, the M02024 may be used with an APD.

The TIA consists of a high gain single-ended

CMOS amplifier with a feedback resistor. The

feedback creates a virtual low impedance at the

input, and nearly all of the input current passes

through the feedback resistor, defining the volt-

age at the output. Advanced CMOS design

techniques are employed to maintain the stability

of this stage across all input conditions. An on-

chiplow dropout linear regulator has been

incorporated into the design to give excellent

noise rejection up to several MHz.

Higher frequency noise is removed by the inte-

grated filter, eliminating the need for an external

capacitor on the photodiode cathode.

The circuit is intended to be configured for use

with PIN photodiodes in the “grounded cathode”

configuration with the anode connected to the

input of the TIA and the cathode connected to

the PINK terminal. The PINK terminal provides

~2V reverse DC bias to reduce the photodiode

capacitance. Operation with an external photodi-

ode bias supply is also possible, as required by

avalanche photodiodes.

A replica of the average photodiode current is

available at the MON pad for photo-alignment,

monitoring average power and 'Loss of Signal'

detection.

For optimum system performance, the M02024

die should be mounted with the photodetector

inside a lensed TO-Can or other optical sub-

assembly.
