This paper presents design techniques for a high power supply rejection (PSR) low drop-out (LDO) regulator. A bulky external capacitor is avoided to make the LDO suitable for system-on-chip (SoC) applications while maintaining the capability to reduce high-frequency supply noise. The paths of the power supply noise to the LDO output are analyzed, and a(More)
The fast Fourier transform (FFT) algorithm is 1 widely used as a standard tool to carry out spectral analysis 2 because of its computational efficiency. However, the presence of 3 multiple tones frequently requires a fine frequency resolution 4 to achieve sufficient accuracy, which imposes the use of a 5 large number of FFT points that results in large area(More)
In this paper, a practical current injection based built-in test (BIT) technique for impedance-matched RF low-noise amplifiers (LNAs) is proposed. A current generation circuit injects the RF test current at the gate of the LNA; this approach has the advantage that the matching network is not affected by the test circuitry. The technique can be used without(More)
Despite the advantages offered by field-programmable gate arrays (FPGAs) for low-power systems requiring flexible computing resources, applications with the lowest power budgets still favor microprocessors and application-specific integrated circuits (ASICs). In order for such systems to exploit FPGAs, an FPGA achieving minimum energy operation is needed.(More)
This paper addresses key technical and economic issues in the design of on-chip measurement circuitry that can be utilized to reduce the cost of testing. A brief outline is provided for research work related to analog/RF built-in selftest (BIST), on-chip instrumentation, and testing requirements of RF front-end blocks. The overview is intended to present(More)
