Latest Patents

Among his latest patents, Lancaster has introduced groundbreaking technologies such as "MDAC based time-interleaved analog-to-digital converters and related methods." This invention focuses on time-interleaved analog-to-digital converters (ADCs) that utilize multiplying digital-to-analog converters (MDACs). In one embodiment, a sample-and-hold circuit captures an input signal and outputs a corresponding voltage. The MDAC then processes this voltage to produce an N-bit digital value and a current representation of the voltage. A phased current generator subsequently creates time-interleaved currents based on this output, which are processed by an array of sub-ADCs to yield an M-bit digital value. This innovative approach provides a robust digital conversion output for the ADC.

Another notable patent is the "Current controlled MDAC for time-interleaved ADCs and related methods." This invention describes current-controlled MDACs designed for time-interleaved ADCs. In this embodiment, the circuit features an MDAC with an amplifier that converts voltage into output current. A variable load, influenced by a digital value, regulates the output current from the amplifier. An array of comparators processes the voltage to produce a digital value for the variable load, representing part of the digital conversion of the voltage. Additionally, a phased current generator creates time-interleaved currents, enhancing the overall functionality of the ADC.
