Publication number: 20240004071Abstract: Embodiments of the present disclosure provide a configurable TIA circuit that can be used as both a single-ended “target TIA” and a differential “reference TIA”. The configurable TIA may include a first circuit to receive an input from a first photodiode (PD), the first circuit comprising a first switch and a first output buffer. The configurable TIA may also include a second circuit to receive an input from a second PD, the second circuit comprising a second switch and a second output buffer. The first and second switches are configured to operate the first and second circuits as independent signal paths via which the input from the first and second PDs can drive the first and second output buffers respectively in a first mode, and in a second mode, combine the input from the first and second PDs into the first output buffer to generate a single differential output.Type: ApplicationFiled: October 17, 2022Publication date: January 4, 2024Inventors: Mark Pude, Murat Ozbas

Publication number: 20230266449Abstract: A method transmits a predetermined signal through a first channel that includes a first digital circuit to produce a first result. The first channel is a functional channel in the FMCW LIDAR system. The method retrieves a second result that is based on the predetermined signal, and determines whether the first result and the second result are nonequivalent. The method then invokes a fault signal in response to determining that the first result and the second result are nonequivalent.Type: ApplicationFiled: January 31, 2023Publication date: August 24, 2023Inventors: Syrus Ziai, Kumar Bhargav Viswanatha, Amol V.

Patent number: 9310817Abstract: Embodiments of the invention generally provide an device that regulates a negative output voltage from a power supply using a positive representation of the negative output voltage. To convert the negative voltage to a positive voltage, the device changes the negative voltage into a current using, for example, a current generator that outputs a current corresponding to the negative voltage received from the power supply. This current is then transferred from the negative voltage domain to the positive voltage domain and is fed through a voltage generator that outputs a positive voltage corresponding to the current. By doing so, the negative voltage output is transformed into a corresponding positive voltage. This positive voltage may then be compared to a positive reference voltage to determine an error signal for adjusting the power supply.Type: GrantFiled: March 31, 2014Date of Patent: April 12, 2016Assignee: SYNAPTICS INCORPORATEDInventor: Mark Pude

Patent number: 9304625Abstract: Embodiments described herein synchronize a switching frequency of switched power supplies with timing events associated with updating a display screen or performing touch sensing. For example, a touch event may be the time needed for a touch controller to scan a plurality of sensing electrodes. Because noise is introduced each time switched power supplies switch between different stages, the touch controller may instruct a power management controller to switch between the stages (i.e., adjust the switching frequency) at the same time during each touch event. Even though the switched power supplies are permitted to introduce noise into the touch system, the noise happens at the same time during each touch event. Accordingly, the effect of the noise is the same for each touch event and is cancelled out. A similar process may be used for synchronizing the switching frequency to display events.Type: GrantFiled: June 28, 2013Date of Patent: April 5, 2016Assignee: SYNAPTICS INCORPORATEDInventors: Imre Knausz, Christopher Ludden, Thomas Mackin, Murat Ozbas, Mark Pude
