Title: Kourosh Pahlavan: Innovator in Ultra-Wideband Technology

Introduction

Kourosh Pahlavan is a prominent inventor based in Cupertino, CA. He has made significant contributions to the field of ultra-wideband (UWB) technology, holding a total of 9 patents. His work focuses on developing systems and devices that enhance the efficiency and functionality of UWB transmitters.

Latest Patents

Among his latest patents is a low power ultra-wide-band transmitter. This invention discloses systems, devices, and methods for an ultra-wide-band transmitter tag capable of operating in different power modes depending on voltage levels and host interruption signals. The transmitter tag includes a power management circuit, a one-time-programmable memory (OTP), a read/write memory, and a state machine for controlling and monitoring the operation of the tag. The tag transitions to high power mode when the power supply reaches a preset voltage level, consuming a higher level of electrical current during this phase. Once high power consumption activities, such as OTP memory downloads, are completed, the tag reverts to low power mode to minimize power consumption.

Another notable patent is for a power-good detector for ultra-wideband transmitters, emphasizing low power consumption. This invention utilizes a transmitter architecture that keeps the transmitter in a deep sleep mode before activation. The transmitter tag comprises a power-good detector, a first regulator, and a second regulator. The power-good detector includes a power-good latch, a ring oscillator, and a ripple counter. When a GPIO pin is disconnected from the ground, the power-good latch sends a Bias_EN signal to the regulator, which then activates the wakeup signal to the ring oscillator. This process initiates clock signals to the ripple counter, which, upon reaching a threshold value, sends a power-good digital signal to the flip flops, allowing the tag to exit reset mode.
