Patent number: 9385747Abstract: A capacitance-to-digital converter circuit utilizes a capacitor bridge circuit to sense a difference in capacitance between sense capacitors and fixed capacitors in the bridge circuit. The sense capacitors vary according to a sensed parameter. Auxiliary capacitor digital to analog converters (DACs) are coupled to the capacitor bridge circuit to cancel the sensed difference. An analog to digital converter (ADC) receives a signal generated by the capacitor bridge circuit and the auxiliary capacitor DACs and converts the received signal to a digital signal. A digital accumulator accumulates the ADC output, whose output represents the difference in capacitance between the sense capacitors and the fixed capacitors. The accumulator output is used to control the auxiliary capacitor DACs to offset the difference in capacitance between the sense capacitors and the fixed capacitors. The accumulator output also provides the basis for the capacitance-to-digital circuit output.Type: GrantFiled: December 18, 2014Date of Patent: July 5, 2016Assignee: Silicon Laboratories Inc.Inventors: Michael H. Perrott, Louis Nervegna

Patent number: 8054125Abstract: A charge pump circuitry for generating a charging voltage for programming a one time programmable (OTP) memory includes a charge pump sub-circuit for generating the charging voltage in a second voltage range when the charging voltage exceeds a threshold level. A precharge circuit generates the charging voltage in a first voltage range when the charging voltage is below the threshold level. A voltage measurement circuit determines the charging voltage. A first control circuit enables the precharge circuit and disables the charge pump sub-circuit in a first mode of operation responsive to the charging voltage being determined to be below the threshold level and disables the precharge circuit and enables the charge pump sub-circuit in a second mode of operation responsive to the charging voltage being determined to exceed the threshold level.Type: GrantFiled: December 31, 2009Date of Patent: November 8, 2011Assignee: Silicon Laboratories Inc.Inventor: Louis Nervegna

Publication number: 20070241832Abstract: A free running clock circuit includes a switching circuit for switching between first and second logic states at a predetermined frequency based upon a trip voltage. The switching circuit has an inherent temperature profile associated therewith. A voltage divider circuit outputs a defined trip voltage that is compensated over the temperature to offset the temperature profile of said switching circuit to provide an overall temperature compensated operation for the free running clock circuit. The voltage divider circuit has a top programmable resistor array connected in series with at least two programmable resistor arrays between two supply terminals of differing voltages.Type: ApplicationFiled: March 31, 2006Publication date: October 18, 2007Inventor: Louis Nervegna

Publication number: 20040139040Abstract: A Hebbian synapse emulation circuit models the conductance of a synapse circuit. In one embodiment, the circuit includes a counter that provides control signals determining the conduction states of electrical pathways, which define the conductance level of the synapse. The counter can increment, decrement, or leave the same, the synapse conductance value based upon potentiation and depression signals that are derived from a voltage that corresponds to the calcium concentration in the synapse. The counter can be coupled to a plurality of synapse circuits on a time-shared basis.Type: ApplicationFiled: January 5, 2004Publication date: July 15, 2004Inventors: Louis Nervegna, Chi-Sang Poon
