The S3TXBIASDSS28LPP circuit has been designed to reduce time to market, risk and cost in the development of analog front-ends. A range of supporting IP blocks such as PLL's, clock buffers, amplifiers, Analog-to- Digital (ADC) and Digital-to-Analog (DAC) converters are also available.
The S3TXBIASDSS28LPP has been implemented on 28nm LPP process. However it is readily portable to any similar manufacturing process. Any activity of this nature can be fully supported.
The Bandgap circuit is a standard implementation using an array of matched PNP transistors to generate the PTAT (Proportional To Absolute Temperature) term.
The Bandgap voltage is used to create accurate bias currents. These bias currents are generated with an external resistor and whereby this resistor can adjust the output full-scale current.
