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 3):
The light-emitting element drive circuit according to  claim 1 ,\n wherein the light-emitting element drive circuit is used for measuring a TOF distance from the light-emitting element drive circuit to a target, the light emission period includes two periods, a distance measurement period for measuring the distance and a setting period for setting a bias voltage of the light-emitting element, the pre-light emission period is provided before each of the two periods, and the circuit further comprises a change portion that changes a drive current of the light-emitting element in each of the two periods.
