A drain terminal of one transistor of each transistor pair in the one or more main buck converter stages may be biased at a first supply voltage. | 2020-04-30 |
20200136638 | NOISE SHAPING IN A DIGITAL-TO-ANALOG CONVERTOR - Systems and methods are disclosed for a signal convertor comprising a resistor or current source coupled to a positive virtual ground node and a negative virtual ground node, wherein the resistor or current source is configured to switch from the positive virtual ground node (VGP) to the negative virtual ground node (VGN), wherein the switching of the resistor or current source results in a shaping of the low frequency noise from the resistor. | 2020-04-30 |
20200136639 | ANALOG TO DIGITAL CONVERTER WITH INVERTER BASED AMPLIFIER - An analog-to-digital converter (“ADC”) includes an input terminal configured to receive an analog input voltage signal. A first ADC stage is coupled to the input terminal and is configured to output a first digital value corresponding to the analog input voltage signal and a first analog residue signal corresponding to a difference between the first digital value and the analog input signal. An inverter based residue amplifier is configured to receive the first analog residue signal, amplify the first analog residue signal, and output an amplified residue signal. The amplified residue signal is converted to a second digital value, and the first and second digital values are combined to create a digital output signal corresponding to the analog input voltage signal. | 2020-04-30 |
