fd115mh FD115MA rev1.3 feb. 9, 2009 p.3 feeling technology functional descriptions refer to the block diagram (figure.1), fd115mh/fd11 5ma is composed of the following building blocks: bias generator the bias generator provides precise, temperature- a nd process-insensitive bias references for the anal og circuit blocks. these references guarantee proper operation of the ic under all conditions specified in this s pecification. oscillator the built-in oscillator provides the clock signal f or the digital control logics power-on reset used to detect the power-up ramp and reset the digi tal circuits to achieve correct operation as soon a s the power is ready. chopper amplifier to achieve a higher magnetic sensitivity the choppe r amplifier structure is adopted in this design. us e of this structure dynamically removes both the offset and f licker noise at the same time. digital control logics hall sensor part C generates controlling signals f or the hall sensor. coil driver part C generates controlling signals f or the coil driver.
