"LiDAR systems have
tight noise margins and
space constraints as well
as complex safety and
design requirements.
Small, dense, highly
integrated receiver-end
hardware eases design
challenges tremendously."

Chapter One: Solving Key Design Challenges
• Include integrated p-channel metal-oxide semiconductor field-effect transistor
(MOSFET) (pFET) and n-channel MOSFET (nFET) for forward/reverse voltage/current
protection; and
• Include programmable undervoltage and overvoltage protection, current-limit
thresholds, and fault response modes.
Maxim supervisory protection circuits defend microcontroller-based systems from power-
related problems that cause the microcontroller to power up or down incorrectly or prevent
the system from not operating as intended.
Maxim temperature sensors reduce current fluctuations when the optical signal has constant
power, which reduces thermal noise in the electrical current that the TIA receives from the
avalanche photodiode (APD).
