This paper describes a binary frequency shift keying (BFSK) transmitter architecture
designed with a technique involving signal generation, mixing, and image rejection for low …

The authors present a review of phase to sine amplitude conversion (PSAC) techniques for
direct digital frequency synthesis (DDFS). Principles of DDFS are first considered, then …

An architectural solution for designing and implementing low THD oscillators is presented. A
digital harmonic-cancellation-block is used to suppress the low-frequency harmonics while a …

A direct digital frequency synthesizer (DDFS) using an analog-sine-mapping technique is
presented in a 0.35-μm SiGe BiCMOS process. We intend to apply the translinear principle …

A 12-bit nonlinear digital-to-analog converter (DAC) was fabricated in a 0.35-mum SOI
CMOS process. The nonlinear DAC can implement a piecewise-linear approximation to a …

Testing is an important part of the design flow in the semiconductor industry. Unfortunately, it
also consumes up to half of the production cost. On-silicon stimulus generators and …

A highly compact 9-bit CMOS direct digital synthesizer without read-only memory that
consumes 8 muW/MHz is described. The circuit is based upon a small nonlinear array of six …

A nonlinear shaping technique for a switched-capacitor (SC) bandpass filter (BPF) based
oscillator yielding enhanced linearity is presented. Usually, for an SC oscillator consisting of …

This paper introduces a sinusoidal signal generation technique using successive integration
of a digital square wave. It utilizes operational transconductance amplifiers (OTAs) and …

In this work, a harmonic-canceling synthesizer for Built-In Self-Test (BIST) applications is
presented. The main contribution is the implementation of the required irrational tap …
