Patent ID: 7562581

Claim:
A system that facilitates reliable sensing in harsh environments, comprising: a sensor that receives a signal; an integrated circuit that processes the signal to provide an output signal, the integrated circuit comprising: an amplifier that amplifies the signal in analog format to provide an amplified analog signal, the amplifier has a bandwidth that is locked to a clock frequency of a clock signal, the clock frequency is proportional to: g m /C where g m represents transconductance of biasing transistors in an oscillator that provides the clock signal and C represents capacitance of a load capacitor of the oscillator; an output circuit portion configured to process the amplified signal to provide the output signal as including at least one of an analog output and a digital output based on the amplified analog signal; and a biasing circuit configured to provide constant-gm biasing to the amplifier and to the output circuit portion to maintain gain and bandwidth thereof over temperature; and an antenna that implements wireless transmission of the output signal.
