A monitoring device comprises circuitry to obtain measurements of one or more pins 116 of a battery system, the circuitry comprising a circuit for monitoring current. The current monitoring circuit detects the absence or disruption of an electrical connection between a battery parameter sensor and the pin. The current monitoring circuit comprises: a differential amplifier 112, with a voltage reference Vref connected to its first input; at least one transconductance 213a, 213b with an output connected to the second input of the differential amplifier and an input connected to an output of the differential amplifier; a current source 214 connected to an output of the transconductance; and an output 125 connected to an output of the transconductance. The transconductance may be a field effect transistor. If there is an open circuit voltage fault on the pin, the current monitor detects this. Also disclosed are: a regulation system for a power on reset; a monitoring device using a received timing ...

A compensation circuit 420 at least partially cancels the offset voltage in an output signal of a force sensor 410. The compensation circuit 420 comprises a voltage divider 422 which receives a bias voltage Vbias that has also been supplied to force sensor 410. The voltage divider outputs a control voltage Vcont, derived from Vbias, and the component mismatch ratio of the voltage divider circuitry is adjustable to correspond to a component mismatch ratio of the force sensor. A current generator 424 receives Vcont and generates a compensation current Icomp. Amplifier circuitry 426 receives the differential signal output by the force sensor and Icomp and outputs a compensated differential output signal in which the offset voltage is at least partially reduced. The voltage divider may have an adjustable ratio of Vcont to Vbias corresponding to a ratio of a quiescent different output voltage of the force sensor to Vbias. A ratio of resistances of the voltage divider circuitry may be adjustable ...

Circuitry for normalising an output signal V_out of a force sensor 130. A bias generator 120 receives a supply voltage V_S and generates a bias voltage V_bias for biasing the force sensor. A control module 140 receives a voltage indicative of the bias voltage and selects a normalization function NORM based on the bias voltage. A processing module 160 receives the force sensor’s output signal V_out and the normalisation function NORM and applies the normalisation function to the force sensor’s output signal. The normalization function may counteract a reduction in a sensitivity of the force sensor due to a lowered bias voltage. The control module may further compare the supply voltage to a threshold voltage and output a control signal based on the comparison to control the bias voltage. The threshold voltage value may be based on a dropout voltage of the bias generator. Also provided is an electronic device comprising said circuitry, a battery to output the supply voltage and a sensor configured ...

Digital to analog converters

Номер: GB0002590513A

The present disclosure provides digital to analogue conversion circuitry that comprises a plurality of selectable conversion elements, wherein a parameter of each of the elements is configured to establish a non-monotonic transfer function between the input digital code and the analogue output signal of the DAC. The conversion elements may be selectable resistances (fig.7), current sources (fig.11) or capacitances (fig.14). The conversion elements, for example the resistors (762, 764, 788 & 768, fig.7) of the resistance network may not follow a binary sequence but instead be arranged to produce a non-monotonic transfer function between the digital input code and the analogue output signal, with the effect that more than one input code may produce a single output value, as shown in fig.8. Such a transfer function is well suited for applications where a particular analogue value must be identified, e.g. where a DC offset is to be corrected or compensated.

A circuit for biasing a sensor 130 (the sensor may be a force sensor) comprises a bias generator 120 which receives a supply voltage V_S and outputs a bias voltage V_bias. A controller 140 compares a voltage indicative of supply voltage V_S and compares it with a threshold voltage V_TH. The controller 140 outputs a control signal CTL to bias generator 120 such that bias generator 120 controls V_bias based on control signal CTL. The threshold voltage may be based on a dropout voltage of the bias generator and the control signal may be a latch signal. The circuit may be used in a tablet, laptop, smartphone, or smartwatch. Also disclosed is a circuit for normalising an output signal of a force sensor comprising a bias generator and a control module which receives a voltage indicative of the bias voltage and selects a normalisation function based on said bias voltage. A processing module 160 receives the force sensor output V_OUT and applies the normalisation function NORM to the output to ...
