Latest Patents

One of his latest patents is the "Large Common Mode Input Range CMOS Amplifier." This invention features a CMOS amplifier input stage that includes an NMOS differential pair connected in parallel with a PMOS differential pair. Each pair is linked to a tail-current transistor of the same type, allowing for adaptive biasing of the differential pairs. This design results in a total combined transconductance that remains approximately constant with changes in input signal level, thereby enlarging the available common-mode input signal range of the amplifier.

Another significant patent is the "Programmable Gain Amplifier." This device includes first and second gain elements connected by an impedance selector, which allows for programmability of the gain of both elements. The impedance selector is strategically placed in series with the output of the first gain element, effectively managing errors introduced in the signal path. This design optimizes bandwidth and noise performance by strategically distributing gain between the amplifier stages.
