Abstract. This paper presents an implementation of an integrated Ultra-wideband (UWB), Binary-Phase Shift Keying (BPSK) Gaussian modulated pulse generator. VCO, multiplier and passive Gaussian filter are the key components. The VCO provides the carrier frequency of 4.1 GHz, the LC Gaussian filter is responsible for the pulse shaping in the baseband. Multiplying the baseband pulse and the VCO frequency shifts the pulse to the desired center frequency. The generated Gaussian pulse ocupppies the frequency range from 3.1 to 5.1 GHz with the center frequency at 4.1 GHz. Simulations and measured results show that this spectrum fulfills the mask for indoor communication systems given by the FCC (Federal Communications Commission, 2002). The total power consumption is 55 mW using a supply voltage of 2.5 V. Circuits are realized using the IHP 0.25 μm SiGe:C BiCMOS technology.

Generator Design

A compact power-on-reset pulse generator (POR-PG) circuit with a low-power and low-voltage operation capability is presented. Proposed POR-PG was fabricated in 0.5 μm 2P3M CMOS process. It was determined from simulations and measurements that proposed POR-PG works supply voltage levels between 1.8 V and 3.3 V and supply voltage rise times between 100 ns and 1 ms. POR-PG has very small silicon footprint. Layout size of proposed POR-PG circuit was 120 μm × 5 μm in 0.5 μm CMOS process. Comparing with other POR-PG circuits in the literature, proposed design enjoys lowest power consumption (< 6 μW), smallest silicon footprint, widest supply voltage range, and additional features such as brown-out detection capability. These achieved by using a unique cascadable POR delay element that consumes very low-power.
