Latest Patents

One of his latest patents is titled "Source follower circuitry including phase shift circuitry." This electronic system features source follower circuitry that functions as an input driver. The design includes a first input transistor, first current source circuitry, and first phase shift circuitry. The first input transistor is configured with a first node coupled to a first voltage node, a second node connected to a first output node, and a gate node linked to a first input node. The gate node receives a first input signal via the first input node. The first current source circuitry is coupled to the first output node and is designed to generate a first bias current. Additionally, the first phase shift circuitry is connected to the first current source circuitry, generating a first phase shift signal to modulate the first current source circuitry, thereby reducing signal drop across the first input transistor.

Another notable patent is "RF DAC with improved HD2 and cross-talk performance by shadow switching in bleeder path." This patent describes a DAC cell that includes first and second transistors, drain-source coupled at a first node, with the gate of the second transistor connected to a data input (D). It also features third and fourth transistors, drain-source coupled at a second node, with the gate of the fourth transistor linked to a complement of the data input (DB). The circuit incorporates first and second shadow transistors, each connected between the first node and ground, with their gates coupled to a switching input (S) and its complement (SB). Furthermore, it includes third and fourth shadow transistors connected between the second node and ground, enhancing the overall performance of the DAC.
