Abstract:
This application relates to transducer apparatus ( 300, 400 ), especially for MEMS capacitive transducers. The apparatus has a voltage bias generator ( 102 ) for receiving a supply voltage (V DD ) and generating a bias voltage (V B ) for biasing a capacitive transducer ( 101 ). A voltage supply path extends between a supply voltage input terminal ( 309 a ) and the voltage bias generator ( 102 ). A programmable trim circuit ( 207 ), in use, controls the bias voltage generated by the voltage bias generator. A first filter ( 301 ) is configured to applying filtering to the voltage supply path. A programming contact pad ( 308 ) is configured to form an external contact of the transducer apparatus when packaged and is electrically coupled to the programmable trim circuit via a signal path that does not include the first filter.

Claim (Index 19):
A transducer apparatus comprising:\n a package structure; an integrated circuit die within the package structure; wherein the integrated circuit die comprises:\n a voltage bias generator for receiving a supply voltage and generating a bias voltage for biasing a capacitive transducer; and \n a programmable trim circuit for, in use, controlling the bias voltage generated by the voltage bias generator; and \n wherein the voltage bias generator and programmable trim circuit are both electrically connected to a first die contact on said die; \n a first filter formed within the package structure on a first substrate, the first filter comprising a filter resistor in series in a voltage supply path between a voltage supply terminal of the first substrate and the first die contact; and a programming contact pad forming an external electrical contact of the packaged structure, the programming contact pad being electrically coupled to a node of the voltage supply path between the filter resistor and the first die contact.
