Latest Patents

One of Tax's latest patents is titled "Configurable last level clock driver for improved energy efficiency of a resonant clock." This invention focuses on a configurable last level driver that is coupled to an inductor-capacitor (LC) tank or resonant clock. The goal is to enhance the energy efficiency of the resonant clock. The design includes a warm-up stage where the last level clock driver stores energy in the LC tank. During the gating stage, the driver can be fully or partially disabled, allowing the stored energy to recirculate into a clock distribution network. In the refreshing stage, the driver replenishes the energy lost during the recirculation process.

Another significant patent is the "Precise and programmable duty cycle generator." This invention produces a user-definable duty cycle clock signal with high precision. The circuit comprises various known elements, including a digital to analog converter (DAC), low pass filter (LPF), and operational transconductance amplifier (OTA). The unique voltage-controlled duty cycle generator (VCDCG) allows for precise duty cycle adjustments over a broad range of operational frequencies.
