The capacitive bias allows for determining the current density precisely by pure timing control. An apparatus is also described for sensing temperature in which a forward-bias diode voltage can be sampled with a capacitor, and large current ratios are possible (e.g., ratio N greater than 1000). Duty cycle of a digital output of the sensor is used to determine the temperature sensed by the sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reverse bandgap reference circuit with bulk diode, and switch capacitor temperature sensor with duty-cycle output","description":"An apparatus is provided which generates a reverse bandgap reference using capacitive bias, which is applied to a single n-well diode.
