An electronic module for generating light pulses includes an electronic card or interposer, a LASER-diode lighting module, and a LASER-diode driver module. The interposer has an edge recess in which the lighting module is completely inserted. The driver module is arranged on top of the interposer and the lighting module. The electrical connections for driving the LASER diodes are obtained without resorting to wire bonding in order to reduce the parasitic inductances.

Electronic module for generating light pulses for LIDAR applications and method for manufacturing the electronic module

A pulse generator circuit includes: an LC resonant circuit coupled between a first node and a reference node; a first switch coupled between the first node and the reference node; a switching network comprising a second switch coupled between the first node and a respective drive node; and drive circuit having outputs coupled to the first switch and to the second switch of the switching network. The drive circuit is configured to, in repeating cycles: close the first switch so that a current flowing through an inductor of the LC resonant circuit increases during a resonant cycle, when the current flowing through the inductor reaches a threshold value, open the first switch, close the second switch of the switching network for a pulse duration time when the first switch is open, and open the second switch at an expiration of the pulse duration time.

An embodiment pulse generator circuit comprises a first electronic switch coupled between first and second nodes, and a second electronic switch coupled between the second node and a reference node. An LC resonant circuit comprising an inductance and a capacitance is coupled between the first and reference nodes along with charge circuitry comprises a further inductance in a current flow line between a supply node and an intermediate node in the LC resonant circuit. Drive circuitry of the electronic switches repeats, during a sequence of switching cycles, charge time intervals, wherein the capacitance in the LC resonant circuit is charged via the charge circuit, and pulse generation time intervals, wherein a pulsed current is provided to the load via the first and second nodes. The charge and pulse generation time intervals are interleaved with oscillation time intervals where the LC resonant circuit oscillates at a resonance frequency.
