Abstract
The effectiveness and optimization of financial services is one of the things that happens when there is financial technology or fintech. Various fintech services have a strategy to attract customers. One of the strategies is to offer promos to potential customers or early customers. Promos given to customers will provide maximum benefits when they use accurate type of promo on a promo provided by fintech services. Knowledge of various fintech services and a lot of promo information will provide an effective alternative for customers to use promos. For this reason, applications or software have been developed to provide information on various e-money and e-wallet services and promos. The method used is Lean UX which consists of 4 stages namely declare assumpts, Develop MVP, run experiments, feedback and user research. The result obtained on this research is a mobile androide application that can display fintech and promo information. Lean UX development is done with 2 iterations and produces features that are validly needed by the user but still need development in terms of User Experience.

Abstract
An ultralow-power and low-complexity impulse radio ultrawideband (IR-UWB) transmitter (TX) is fabricated in the low-cost 180-nm United Microelectronics Corporation (UMC) CMOS technology. The TX offers control of the power spectral density (PSD) by using a tunable pulse generator and a controllable switched oscillator. It supports on-off keying (OOK) coding and occupies a total die area of 0.35 mm(2). The measured results show the transmitter output amplitude of 130 mVp-p with the pulse width of 1.0 ns, and the PSD with 10-dB bandwidth from 3 to 8.8 GHz. The total dc power consumption is 0.6 mW, corresponding to the energy consumption of 3 pJ/pulse at 200-MHz pulse repetition frequency.
