Abstract
Described herein are solid state sensors for measuring various physical parameters. The solid state sensors may be used in systems, devices, and methods for controlling blood flow or for measuring (e.g., monitoring) blood pressure. In some instances, the method may include obtaining a first count number indicating a number of oscillations at a first ring oscillator circuit during a sample period. The first ring oscillator circuit may be associated with a sensor and oscillates at a first oscillation rate. The first oscillation rate may be based on a first set of physical parameters and a second physical parameter. The method may further include obtaining a second count number indicating a number of oscillations at a second ring oscillator circuit during the sample period. The second ring oscillator circuit may be associated with the sensor and oscillates at a second oscillation rate. The second oscillation rate may be based on the first of physical parameters but not the second physical parameter. The method may further include determining a value associated with the second physical parameter at the sensor based on the first count number and the second count number.
