Abstract:
There is provided a VCSEL drive circuit that causes a VCSEL to emit pulsed light in a light emission period, including a drive adjustment unit that adjust a first voltage which is a voltage of drains of a PMOS transistor and an NMOS transistor in a constant current circuit and a second voltage which is a voltage of a drain of an NMOS transistor that drives the VCSEL to be the same voltage in a pre-light emission period before the light emission period.

Claim (Index 2):
The light-emitting element drive circuit according to  claim 1 ,\n wherein the drive adjustment unit includes a differential amplifier to which the first voltage and the second voltage are input and a capacitor that holds an output voltage of the differential amplifier at the end of the pre-light emission period, and feedback is applied to the differential amplifier so that the first voltage and the second voltage input to the differential amplifier become the same voltage in the pre-light emission period.
