Latest Patents

Xiao Shi's latest patents include the **Transconductance-enhancing passive frequency mixer** and the **Stochastic Time-Digital Converter (STDC)**.

The Transconductance-enhancing passive frequency mixer comprises a transconductance amplification stage, a frequency mixing stage, and an output transresistance amplifier. This design features a pre-amplification transconductance-enhancing structure that greatly enhances transconductance, allowing for the same transconductance value at lower bias currents. By modulating a radio-frequency current through the frequency mixing stage, it generates a mid-frequency current signal, which is then converted into a voltage output. The transresistance amplifier within this system further reduces input impedance while improving current utilization efficiency. The frequency mixer is characterized by low power consumption, high conversion gain, and excellent port isolation.

The Stochastic Time-Digital Converter includes an input switching circuit, an STDC array, and an encoder. It utilizes two clock signals processed through the input switching circuit, which outputs a trigger control signal to the encoder. Each comparator within the STDC array independently assesses the clock signals' speeds, providing data to the encoder for analysis. This innovative design utilizes the stochastic characteristics of the STDC to effectively double the number of equivalent comparators, mitigating the impact of circuitry mismatches and environmental variations.
