Latest Patents
One of his latest patents is titled "Complex filtering/AGC radio receiver architecture for low-IF or zero-IF." This invention presents a low power IF strip architecture suitable for Zero-IF (ZIF) or low-IF (LIF) radio receivers. It is designed for filtering and amplifying received signals. The apparatus includes multiple sequentially connected complex filter/amplifier stages. Each stage features a complex filter with one or more poles and an automatic gain controlled amplifier (AGC). The AGC can operate with fixed minimum and maximum gains, and a control circuit generates a gain control signal to manage the amplifier gain. This design allows for efficient power savings while effectively amplifying the desired signal and attenuating interference.
Another significant patent by Cherry is the "Low-voltage transconductance amplifier/filters." This invention addresses the challenges faced by wireless communications devices, which must manage a wide range of useful signal levels while coping with large interfering signals. The transconductance amplifiers/filters described in this patent utilize feedback mechanisms that do not require signal conversions. As a result, these cells maintain high linearity and can operate at low voltage, making them ideal for modern communication systems.
