This paper proposes a fully digital sensor interface. For this, an analog to digital converter (ADC) and time to digital converter (TDC) based on a common time based ADC (TAD) architecture has been investigated. It is concluded that the proposed fully digital time-based ADC architecture can also be operated as TDC. The fully digital circuit has a ring delay line (RDL), latch, encoder and a synchronous...
The CORDIC (COrdinated Rotation DIgital Computer)[1] algorithm provides an efficient and accurate platform to compute various trigonometric, linear and non-linear functions using only shift-add operations. This paper presents the implementation of CORDIC algorithm on a configurable architecture to port various transforms which forms the heart of image and signal processing applications. We shall demonstrate...
This paper proposes a novel reconfigurable multiplierless architecture that could be operated as a convolver, FIR filter, adder, multiplier and running average computing unit. The proposed multiplierless architecture uses only shift-and-accumulation resulting in significant saving in the gate-count making it suitable for low power applications as required in wireless sensor networks(WSN), body sensor...
Ultra-Wide Band (UWB) technology has recently become a viable option for wireless applications that require high data-rate and ultra low power demand. This paper presents an all-digital UWB transmitter architecture using 0.18μm CMOS. It employs a delay line based architecture that works with Pulse Positioning Modulation (PPM), On Off Keying (OOK) and Delay Based Binary Phase Shift Keying (DB-BPSK)...
