Design of a variable gain, high linearity, low power baseband filter for WLAN transmittersRanganathan, Sachin 15 April 2003 (has links)
A variable gain, high linearity, low power baseband filter for WLAN applications
is implemented in a 1.5 V 3 V 0.15 ��m CMOS process. This fourth-order
low-pass filter, which is introduced in the transmit channel as a reconstruction filter
between the D/A converter and the mixer, has a measured cut-off frequency of
9 MHz. The active-RC configuration has single amplifier biquads (SABs) to save
power and is implemented using three-stage opamps with nested-Miller compensation
for better linearity. It also features a special ��-to-Tee transformation network
for the resistor arrays, used for frequency or gain trimming, in order to obtain higher
linearity than conventional Sallen-Key circuits. The measured THD for a 2 V [subscript p-p]
signal at 1 MHz is -72 dB. / Graduation date: 2004

Design of CMOS switched-current filtersFiez, Theresa S. 14 June 1990 (has links)
The design and implementation of Switched-Current (SI) ladder filters is
described. SI filters require only a standard digital CMOS process and the power
supply voltage requirement is low. SI circuits also can be potentially operated at
higher frequencies than Switched-Capacitor (SC) filters due to the low-impedance
wideband nodes of the current mirrors. A simple method has been developed to
design SI ladder and biquadratic fllters with maximum dynamic range that leverages
the well-established design methodologies of SC filters. A standard digital 2-micron
n-well CMOS process has been used to implement two high-order ladder filters and
two biquadratic filters. Simulations accurately predict the measured results of the
first integrated SI filters. The area and power dissipation are comparable to the
switched-capacitor technique.
Analysis of the factors that effect dynamic range in SI filters is presented.
The factors that contribute to harmonic distortion in the current-mode circuits are
characterized and the relationships to maximum signal size are established. Using
measurements of the input-referred noise from SI filters, the dynamic range is
obtained. / Graduation date: 1991

Switch capacitor filter design aidsMcCall, William L. January 1982 (has links)
Two aids for the design of switched-capacitor filters (SCFs) are examined: breadboard modelling and computer simulations. A breadbroad was constructed based upon the same passive prototype of a seventh-order integrated filter. The breadboard met the original design specifications better than the integrated filter because the schematic and parasitics of the integrated filter were unknown.
Three computer programs, SPICE, DIANA, and TCAPS, are compared to determine their abilities and limitations in SCF design. SPICE is of limited value since it models switched capacitors as resistors. DIANA and TCAPS directly simulate the digital nature of switched capacitors, so they track in their predictions of
1) increased passband ripple,
2) increased cutoff frequency,
3) increased third notch frequency,
4) increased OBR.
On the basis of this comparison, it is not possible to determine if DIANA or TCAPS is the better program. However, both DIANA and TCAPS simulate SCFs far more accurately than SPICE. / Master of Science
