High speed pulse modulation system

A sensor system comprising:

• a sensor including an oscillator configured generate a oscillation signal having an oscillation frequency, the sensor being configured to measure an environmental condition and to generate a signal corresponding to the measured environmental condition based on the oscillation frequency;
• and
• a controller configured to generate a bit stream to control the oscillation frequency of the oscillator and to process the signal corresponding to the measured environmental condition, the controller including a modulator driven by a first clock signal having a first clock frequency and a second clock signal having a second clock frequency different from the first clock frequency, the modulator including:
• a memory configured to store oscillator control values;
• a bit streaming loader (BSL) configured to:
• receive one or more of the oscillator control values from the memory;
• generate one or more corresponding bit values based on the one or more of the oscillator control values;
• and
• a bit streaming block configured to:
• generate a bit stream based the one or more bit values generated by the BSL;
• and
• transmit the bit stream to the oscillator of the sensor to control the oscillation frequency of the oscillator.

A modulator operable to control an oscillator of a sensor, the modulator comprising:

• a memory driven by a first clock signal having a first clock frequency, the memory being configured to store oscillator control values;
• bit streaming loader (BSL) driven by the first clock signal and a second clock signal having a second clock frequency greater than the first clock frequency, the BSL being configured to:
• receive one or more of the oscillator control values from the memory;
• and
• generate one or more corresponding bit values based on the one or more of the oscillator control values;
• a bit streaming block driven by the second clock signal and being configured to:
• generate a bit stream based the one or more bit values generated by the BSL;
• and
• transmit the bit stream to the oscillator of the sensor to control the oscillation frequency of the oscillator;
• and
• a trigger generator driven by the second clock signal and being configured to generate a trigger signal to process a sensor signal from the sensor corresponding to an environmental condition measured by the sensor.
