Latest Patents

One of his latest patents is the "Low power current integration DAC ramp settling assist circuit." This invention features a ramp generator that includes an operational amplifier designed to generate a ramp signal. The integration current source is coupled to a first input, while a reference voltage is connected to a second input of the operational amplifier. A feedback capacitor and a reset switch are integrated between the first input and the output of the operational amplifier. The reset switch is activated to reset the ramp generator, and a ramp event is configured to be generated in the ramp signal at the output of the operational amplifier when the reset switch is turned off. Additionally, an assist current source is connected between the output of the operational amplifier and ground, conducting assist current in response to the reset switch being turned off.

Another significant patent is the "Trimming control circuit for current integration ramp DAC settling assist circuit." This invention also utilizes a ramp generator with an operational amplifier to produce a ramp signal. An integration current source is linked to a first input, and a reference voltage is connected to a second input. A monitor circuit generates an output flag based on a comparison of the first and second inputs. The trimming control circuit produces a trimming signal in response to the output flag, while an assist current source conducts assist current from the output of the operational amplifier to ground based on the trimming signal.
