Patent
Discrete time operational transconductance amplifier for switched capacitor circuits
Kentaro Yamamoto,Lennart Mathe +1 more
TL;DR: In this article, a discrete-time operational transconductance amplifier (OTA) with large gain and large output signal swing is described, which includes a clocked comparator and an output circuit.
Patent
Excess loop delay compensation (elc) for an analog to digital converter (adc)
TL;DR: In this article, a quantizer is configured to convert an analog input signal to a digital signal at the summing junction, and the quantizer includes a plurality of excess loop delay (ELD) compensation paths coupled to the sum-ming junction.
Patent
Reducing signal dependence for CDAC reference voltage
Seyed Arash Mirhaj,Sameer Wadhwa,Dinesh Jagannath Alladi,Kentaro Yamamoto,Xiaoke Wen,Masoud Ensafdaran,Weihua Chen +6 more
TL;DR: In this article, the authors propose to split a decoupling capacitor into a plurality of capacitors smaller in size than a size of the decoupled capacitance, isolating at least one of the plurality from a sampling buffer coupled to the reference voltage during a conversion phase.
Patent
Alias rejection through charge sharing
TL;DR: In this paper, an example apparatus for alias rejection through charge sharing is disclosed, which includes a filter-sampling network, a digital-to-analog converter, and a charge sharing switch.
Patent
Time-to-digital converter (TDC)-based quantizer
TL;DR: In this paper, the authors provide apparatus and techniques for analog-to-digital conversion using a TDC, where a quantizer may include at least one first capacitive element and a set of switches configured to selectively couple a first terminal and a second terminal of the at least 1 first capacitor element to at least a single input voltage source.
