Abstract: A power amplifier amplifying an input signal to generate an output signal, comprising a cascode unit and a bias circuit. The cascode unit comprises a cascode stage, a first input stage, and a second input stage. The cascode stage generates the output signal. The first input stage, in cascode with the cascode transistor, has a first signal input to be biased to provide a first amplifier gain. The second input stage, in cascode with the cascode transistor, has a second signal input to be biased to provide a second amplifier gain. The bias circuit, coupled to the first and the second input stages comprises first and second switches. The first switch, coupled to the first input stage, is switched on to bias the first input stage with a bias voltage. The second switch, coupled to the second input stage, is switched on to bias the second input stage with the bias voltage.

Abstract: The present invention provides a fingerprint sensing mechanism using a two-dimensional thermoelectric sensor array to capture the thermal image related to the ridges and valleys on the finger, wherein its fabricating method is totally compatible with integrated circuits processing. Using the body temperature of a human being as the stimulation source for biometrics, a temperature difference is produced from a ridge of a fingerprint contacting the thermoelectric sensor and the temperature gradient is converted into an electrical signal. A plurality of thermoelectric sensors arranged in a two-dimensional array forms a fingerprint sensor so as to obtain the electrical signal output of the ridge profile of the fingerprint.
