The analysis of power consumption across varying supply voltage from 1 V to 1.4 V and temperatures ranging from -40 \u00b0C to 120 \u00b0C shows the efficiency and stability of the iptat current (PTAT source) and the ibias, the iref current from the ISRC (current source) block. \nThis PTAT current source generates 16.08 \uf06dA of the iptat current and consumes 67 \uf06dW power at 1.2 V supply, at room temperature (27 \u00b0C). The ISRC block generates the iout, ibias and iref currents. The temperature coefficient of the iptat current is determined, and it has a temperature coefficient of 3.78 kppm/\u00b0C. The iout (output current) current of 2 kppm/\u00b0C temperature coefficient is obtained by adding the ibias current with the iptat current in specific proportion, which is then further used for driver of Bluetooth transmitter.\nAfter the line sensitivity analysis, the iptat current indicates the lowest sensitivity to supply voltage variation of 0.28 %/V, whereas the iout current is the most sensitive with line sensitivity of 0.99 %/V. The noise analysis is done over the frequency range of 10 Hz to 1 GHz, also the PSRR analysis showed a that the iptat current possesses the PSRR of 50 dB at 100 kHz. \nA Monte Carlo simulation involving 1000 runs quantifies the mismatch variations in key parameters, with 3\u03c3 variation of a 4.9 % mismatch observed for the iout current and a 3\u03c3 variation of a 6.1 % mismatch for the iptat current. These findings underscore the importance of robust design methodologies to minimize mismatch and enhance circuit reliability.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2024-09-27T05:26:07Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-09-27T05:26:07Z (GMT).
